THAT WORKED!  Thanks!

By the way, is it possible to get information about eCos threads in
GDB-Insight?  Insight gives me an error when I invoke "View->Thread-list".
Perhaps it's my GDB/Redboot stub that's somehow broken?
Thanks,

Worked?! It shouldn't have changed anything except to output some debug
info! Weird. Sounds like some sort of timing bug if this fixes it (which
potentially relates to other problems you've seen.

It must be because this normally works.
