Kernel level support for threading > may address this. Since most FreeBSD machines are not yet SMP, the advantage of multiple processors is probably not an issue, so I would most likely not consider threads on a FreeBSD box... Kernel level support for threading (or threads in general, for that matter) may not be particularly portable in any case. I guess I would not consider this viable unless someone told me up front that there was a single platform that was being targeted, and there was a clear advantage to the use of threads in the given context, and the thread support on the platform in question was known to be good. But Andrew only asked for some general theory on the subject. :-) ... JG
