(I've switched the thread of this, because the Future of ProofGeneral is a 
serious issue in its own right.)

The plan for the comining release (which will happen within a couple of 
weeks) is to keep the status-quo of Isabelle2011-1.  This means 
ProofGeneral will be not more buggy than everybody is used to anyway. 
Today I've made some quick tests with Emacs on Mac OS X already, and it 
looks not worse than last fall.

In the longer run, the proponents of ProofGeneral need to find a solution 
for themselves, and organize a maintenance scheme -- I have pointed this 
out several times before.  BTW, there is quite a lot of recent activity on 
the ProofGeneral CVS, so it is not quite dead yet.
