31 folded libthread into libc and has led to some fundamental changes
32 in the rules by which code in libc must be developed and maintained.
34 All code in libc must be both MT-Safe and Fork-Safe
35 and where possible (almost everywhere), Async-Signal-Safe.

112 lmalloc()/lfree() is a small and simple power of two allocator.
123 calls to fork() and forkall(), but it also serializes calls to
124 thr_suspend() (fork() and forkall() also suspend other threads),
125 and furthermore it serializes I18N calls to functions in other
