It stands for "Native POSIX Thread Library" It is a new threads subsystem
that is included in Linux 2.6 that Red Hat has backported into their 2.4
kernels. It has some performance advantages and has more correct POSIX
behavior (especially in terms of signal handling.) over the older

The choices seem to be to use a Linux 2.6 kernel, or to use a Red Hat 2.4
kernel with NPTL backported into it. (the earliest releases of Red Hat 9
had problems, but they seem to have been fixed in later kernel and glibc
The older LinuxThreads library has a non-standard threading function
pthread_kill_other_threads_np that can be used as a workaround to notify
other threads of termination.
