With the work that John Dyson has done (is doing 8-) on kernel threads, libc_r can die and be replaced by libpthread + libc. This is made possible because any thread can block on a syscall and the kernel will schedule another thread. Without kernel threads, blocking syscalls are problematic to libc_r, as you know 8-). Of course there is still a lot of work required to make libc re-entrant.
