This class contains all the useful informations about the observed
event. However, the presence of each field is not guaranteed and
depends on the type of event. In effect, some fields are irrelevant
for some kind of event (for example 'cookie' is meaningless for
IN_CREATE whereas it is mandatory for IN_MOVE_TO).
The possible fields are:
- wd (int): Watch Descriptor.
- mask (int): Mask.
- maskname (str): Readable event name.
- path (str): path of the file or directory being watched.
- name (str): Basename of the file or directory against which the
event was raised in case where the watched directory
is the parent directory. None if the event was raised
on the watched item itself. This field is always provided
even if the string is ''.
- pathname (str): Concatenation of 'path' and 'name'.
- src_pathname (str): Only present for IN_MOVED_TO events and only in
the case where IN_MOVED_FROM events are watched too. Holds the
source pathname from where pathname was moved from.
- cookie (int): Cookie.
- dir (bool): True if the event was raised against a directory.

There is three kind of processing according to each event:
1. special handling (deletion from internal container, bug, ...).
2. default treatment: which is applied to the majority of events.
3. IN_ISDIR is never sent alone, he is piggybacked with a standard
event, he is not processed as the others events, instead, its
value is captured and appropriately aggregated to dst event.

By default this method only reports warning messages, you can overredide
it by subclassing ProcessEvent and implement your own
process_IN_Q_OVERFLOW method. The actions you can take on receiving this
event is either to update the variable max_queued_events in order to
handle more simultaneous events or to modify your code in order to
accomplish a better filtering diminishing the number of raised events.

Coalescing events. Events are usually processed by batchs, their size
depend on various factors. Thus, before processing them, events received
from inotify are aggregated in a fifo queue. If this coalescing
option is enabled events are filtered based on their unicity, only
unique events are enqueued, doublons are discarded. An event is unique
when the combination of its fields (wd, mask, cookie, name) is unique
among events of a same batch. After a batch of events is processed any
events is accepted again. By default this option is disabled, you have
to explictly call this function to turn it on.
@param coalesce: Optional new coalescing value. True by default.

This notifier inherits from threading.Thread for instanciating a separate
thread, and also inherits from Notifier, because it is a threaded notifier.
Note that every functionality provided by this class is also provided
through Notifier class. Moreover Notifier should be considered first because
it is not threaded and could be easily daemonized.

size to read becomes >= threshold. If != 0, you likely
want to use it in combination with an appropriate

keep looping without really reading anything and that
until the amount of events to read is >= threshold. At
