The noFLTKThreads=1 option does not affect anything that is not
in the widgets plugin. This may be a Mac-specific issue. What happens
if you delete the plugin ?
By the way, note that using the same CSOUND* instance from multiple
threads at the same time is often unsafe (for example, if one thread
performs and another tries to create a note event, sometimes a crash
may occur). You may need to synchronize access to the Csound API.

Which fix was that ? I only see the #ifdef for DIRENT_FIX, and removal of
old unused Mac functions committed by you, but those changes still seem to
be there.
