[Twisted-Python] 100% CPU on high opened descriptors

[Reza Lotun]

Can you not do a:

from twisted.python import log
from twisted.internet import reactor
log.msg('My reactor is: %r' % repr(reactor))

somewhere in your code to determine it?

Are you running your application with twistd? You can pass a reactor
implementation via the '-r' option.
