100% cpu usage on some systems - twisted POLLIN

[Antoine Martin]

The pygtk bug is ​here
I had originally created a twisted bug ​here - but the problem is not in twisted.

And here is the Fedora bug: ​660137

Gentoo bug: ​353599

Ubuntu bug: ​664920

Debian already has a patch for squeeze (against 2.17.0-4):
​pygtk-wakeupfd-fix.patch

FreeBSD: ​bug 154755

So, I believe we should just leave it to the distributors to ship patched versions of the libraries we rely on rather than trying to workaround the issue (not even sure it is possible to do so)

However: if you want to use the fixed PyGTK RPMs/DEBs we have made using the above patch, please download them manually from:
​http://winswitch.org/dists/

(as this is a system package - we will not push it to you automatically: this is your distribution's job)

This seems to be fixed in r3423 following the discussion on ​bug 4658 at twistedmatrix.com - at last!

Reverted in r3424 - this has too many side effects, the proper solution is for distributions to fix their version of PyGTK.
The PyGTK patch is available ​here

Fix has now been committed to pygtk trunk: ​commit 4cbd3c031289775f365c247f949d91facac4ba82

Still waiting for most distros to pick it up...
