New description:

 The version of Twisted currently used in Sage is old and obsolete;
 moreover it is buggy, as our extensive tests involving running  labs for
 120 students show. The crashes of the notebook webapp go away after the
 upgrade to twisted 11.

 The twisted package is now included in the flask sagenb (#11080), so this
 ticket just has the patch to remove the twisted spkg.

 See http://groups.google.com/group/sage-
 devel/browse_thread/thread/98c53d17166da1b9 for the sage-devel vote.

 '''apply''': [attachment:trac-11874-remove-twisted.3.patch] to the sage
 root repository,  '''remove''' the '''twisted''' spkg from the standard
 spkgs, and
 '''replace''' the '''sage-***''' spkg in  the standard spkgs by
 [http://web.spms.ntu.edu.sg/~dima/tmp/sage-5.0.beta8.spkg this one].

 (or you can patch the {{{sage-***.spkg}}} with the attached patch)

Comment:

 I have successfully modified {{{sage-***.spkg}}} to build with twisted
 removed. See the patch for review above.
 I basically cut a piece of {{{sage.misc.fpickle}}}, it into
 {{{sage-***.spkg}}}, and import it instead of {{{twisted}}} in
 {{{setup.py}}}. It is only needed for building the sage python module.
