A quick question: Do all the widgets that do that sort of thing open
separate threads or are they capable of sharing one extra one? I
noticed the same happens with progress bars, etc.

I've written a document app that creates two threads for each
document. When the doc closes, the threads terminate. But an extra
thread sometimes appears. I don't know what it is. Is it part of the
DO class system, or have I failed to clean up my threads properly?
Here is its stack trace:
#0 0x9003eaa8 in semaphore_wait_signal_trap
#1 0x9003e8c4 in pthread_cond_wait
#2 0x90824180 in -[NSConditionLock lockWhenCondition:]
#3 0x93081388 in -[NSUIHeartBeat _heartBeatThread:]
#4 0x9081cd38 in forkThreadForFunction
#5 0x90020d48 in bootstrap_status
AFAIK, this thread is used for instance to make the default button
throb.
I have occasionally seen this thread cause crash with applications. It
can also make application hang.
