(Running OS X Panther 10.3.5)
Each time a syntax check is performed, a new thread is created
and never destroyed. While typing in the editor, I observed the
tread count increase with each syntax check. I can duplicate this
repeatedly on different OS X machines.
After a day, or so, I can have 2000+ threads. My attention was
drawn to this problem when when my PowerBook fan kicked in,
which it rarely does.
