Class t.i.p.PollReactor(posixbase.PosixReactorBase):

A reactor that uses poll(2).

Instance Variables	_poller	A `poll` which will be used to check for I/O readiness.
	_selectables	A dictionary mapping integer file descriptors to instances of `FileDescriptor` which have been registered with the reactor. All `FileDescriptors` which are currently receiving read or write readiness notifications will be present as values in this dictionary.
	_reads	A dictionary mapping integer file descriptors to arbitrary values (this is essentially a set). Keys in this dictionary will be registered with `_poller` for read readiness notifications which will be dispatched to the corresponding `FileDescriptor` instances in `_selectables`.
	_writes	A dictionary mapping integer file descriptors to arbitrary values (this is essentially a set). Keys in this dictionary will be registered with `_poller` for write readiness notifications which will be dispatched to the corresponding `FileDescriptor` instances in `_selectables`.

Method	__init__	Initialize polling object, file descriptor tracking dictionaries, and
Method	addReader	Add a FileDescriptor for notification of data available to read.
Method	addWriter	Add a FileDescriptor for notification of data available to write.
Method	removeReader	Remove a Selectable for notification of data available to read.
Method	removeWriter	Remove a Selectable for notification of data available to write.
Method	removeAll	Remove all selectables, and return a list of them.
Method	doPoll	Poll the poller for new events.
Method	getReaders	Return the list of file descriptors currently monitored for input
Method	getWriters	Return the list file descriptors currently monitored for output events
Method	_updateRegistration	Register/unregister an fd with the poller.
Method	_dictRemove	Undocumented
Method	_doReadOrWrite	Undocumented
