The main problem I had was about asyncore getting signals from exiting
childs of os.popen, as solaris delivered these to the first waiting
thread and not the thread that had spawned the child.

It had a simple 2 or 3 line fix.

I also have some problems with database (oracle) transactions never
committing/aborting but I have these on linux/postgresql as well, so
this is not solaris specific.
