[Seaside] 3.0rc hangs on OS-X 10.5.8 and recover lost changes doesn't work.

[Stephan Eggermont]

The behavior of auto-completion in 3.0rc is not very nice on OS-X  
(10.5.8).
Once in a while it just takes a lot of time to react, and it manages  
to hang the
image. A user interrupt shows it's busy in weakset once, and  
thereafter no
longer responds to user interrupts.

That doesn't combine well with "recover lost changes" not working.
How is that supposed to work? Filing in a set of changes doesn't
seem to do anything at all.
