[Twisted-Python] twisted run out of file descriptors

[Alec Matusis]

I changed reactor to poll(), and it has sucessfully surpassed 1024 file
descriptors limit, while the load on the machine did not increase
significantly from select() based reactor.

Thanks everybody for the help

Sounds like you might be confused - if someone had told you that
select() is faster than *polling*, that would be accurate - the
terminology is confusing because "polling" means "repeatedly checking
for input in a busy-loop".  In this context, "polling" is actually the
opposite of "calling poll()".

poll() is simply a better version of select().  The only reason it is
not the default reactor is that there are some obscure places where
select() exists and it does not.  I am not sure if this is even relevant
any more, since I don't know if any such place can build recent versions
of Python.
