[Medusa-dev] improvements to select_trigger

[Jeremy Hylton]

I wanted to mention that we've fixed a bunch of bugs in a forked copy
medusa's select_trigger during ZEO development.  (ZEO is a Zope/ZODB
RPC protocol built on tope of asyncore.)  I thought I'd mention it on
this list in case you want to update the version in medusa.

I don't know if I remember all the bugs fixed.  I recall that the
trigger can fail unexpectedly if a singal interrupts the recv() in
handle_read() and that there was some problem with closing the trigger
more than once.

The gory details are in the CVS log here:
