Enter a polling loop that only terminates after all open channels
have been closed. All arguments are optional. The \var{timeout}
argument sets the timeout parameter for the appropriate
\function{select()} or \function{poll()} call, measured in seconds;
the default is 30 seconds. The \var{use_poll} parameter, if true,
indicates that \function{poll()} should be used in preference to
\function{select()} (the default is \code{False}). The \var{map} parameter
is a dictionary whose items are the channels to watch. As channels
are closed they are deleted from their map. If \var{map} is
omitted, a global map is used (this map is updated by the default
class \method{__init__()}
-- make sure you extend, rather than override, \method{__init__()}
if you want to retain this behavior).

Enter a polling loop that terminates after count passes or all open
channels have been closed. All arguments are optional. The \var(count)
parameter defaults to infinity, resulting in the loop terminating only
when all channels have been closed. The \var{timeout} argument sets the
timeout parameter for the appropriate \function{select()} or
\function{poll()} call, measured in seconds; the default is 30 seconds.
The \var{use_poll} parameter, if true, indicates that \function{poll()}
should be used in preference to \function{select()} (the default is
\code{False}). The \var{map} parameter is a dictionary whose items are

map. If \var{map} is omitted, a global map is used (this map is updated
by the default class \method{__init__()} -- make sure you extend, rather
than override, \method{__init__()} if you want to retain this behavior).
Channels (instances of \class{asyncore.dispatcher}, \class{asynchat.async_chat}
and subclasses thereof) can freely be mixed in the map.
