Thanks for the report.

It looks like it's not our fault though.  Attached is a non-Allegro
example that suffers from the same problem.  The `popen' hang appears
to happen when a thread is started from a function that is located in
a dynamically linked library.  Unless there is some magic command-line
option that will fix it?

(To run the program, you'll have to ``export LD_LIBRARY_PATH=.'')
