One possibility might be NSPR, the Netscape Portable Runtime, which provides platform-independent threads and I/O on Mac, Win32, and Unix. Perhaps a thread implementation could be written that sat on top of NSPR, in addition to the existing pthreads implementation. See http://www.mozilla.org/docs/refList/refNSPR/.

NSPR looks rather promising! Does anyone has any experiences with it? What I'd also be interested in is experiences in how it interacts with the "real" I/O system, i.e. can you mix and match NSPR calls with normal os calls, or will that break things? The latter is important for Python, because there are lots of external libraries, and while some are user-built (image libraries, gdbm, etc) and could conceivably be converted to use NSPR others are not... -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen@oratrix.com | ++++ if you agree copy these lines to your sig ++++ www.oratrix.nl/~jack | see http://www.xs4all.nl/~tank/spg-l/sigaction.htm
