The code works fine. It's like saying that libc is broken for multithreaded programs. It's not broken, it's just that the program that is using libc (vs. libc_r) is not designed correctly to work with libc. > If I link the plugin java_vm with libc and tell it to use green > threads, it *immediately* dies due to a null-pointer reference in > green_sigprocmask, a *BSD-specific function.
