I was thinking that would be nice too, until I visited http://www.freebsd.org/kse/ and found it was already done. To quote: In order to use KSE in an application, you need to link it against libpthreads, which is not built by default. To build and install it on your system, either run make all install from /usr/src/lib/libpthread (if you have sources installed on your system), or check out the libpthread and libc modules from CVS. You don't need to rebuild libc, but the libpthread makefiles refer to parts of the libc sources. Linking an application against libpthread is straighforward. In its makefiles, change the -pthread option to -lpthread and relink. Alternatively, you can copy libpthread.so on top of libc_r.so, but this is not recommended until libpthread.so becomes a bit more stable. I'm going to give it a whirl since Jeff's overnight commits to libthr make my system reboot every time I run mozilla. How much worse can libpthread be? :) *tinker, tinker* Geoff
