The following reply was made to PR bin/26307; it has been noted by GNATS.

Noatun is also not thread-safe. The fact that pthreads is implemented in user-space makes it impossible to change the reference for the appropriate syscalls. At least this is true for 4.x. Hopefully 5.x will put pthreads in the kernel. This problem will be revisited for KDE 2.2, where the author of aRts is going to offer non-threadsafe versions for the libraries in aRts which are written in a threadsafe manner. </paraphrase> I may not remember something above correctly, but it makes sense to me. --=20 wca To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
