Hi,

Just thought I'd chime in at this point -- I've adapted the portable
machine context switching code from GNU Pth into a cothread library that
is actively used by one of GStreamer's schedulers. It's in a standalone
cvs module, cothreads/ under gstreamer's sf cvs repository. The intent
is to do some more work on it and eventually propose it for inclusion
into GLib. It's pretty good right now, but I need to run through it and
clean up a few things and write some docs.

Anyway, wanted to let you know of this project, as you brought up the
issue.

regards,

wingo.
