6f6c26d232 Make sure brk doesn't clobber existing mappings 
This was causing the random node segfaults. Node does manual ASLR, so it
would randomly pick an address for a memory mapping near the brk region,
then later something would raise the brk and clobber that mapping,
replacing it with zeroes. Shortly afterward something would crash on a
null pointer.

Took a lot of digging around in rr to find this. The crash is never
directly connected to the brk call, of course. I set a watchpoint on the
pointer that got clobbered and saw it had been zero since the page was
mapped, but it took setting a watchpoint on the pointer to that pointer
to find that when it was mapped before that and was valid at that point.

At this point I'm ready to say node is fixed! #90

0032099894 Improve the debug dump functions 
dump_maps doesn't overflow the buffer anymore. dump_stack lets you
specify how many lines of output you want.

aa8810cb8f Implement FIOCLEX/FIONCLEX

Node inspector immediately closing any connections it gets. #90

023d692f58 Better handle unknown errors 
They now get logged instead of causing a crash. The program seeing the
error might even print the error number if we're lucky.

640017278e Fix locking issues with CPU refactor

read-locked, and it would write-lock mem to clean up jetsam.

fcb0599aa5 Squash some warnings 
arch_prctl was never useful for anything, _GNU_SOURCE is needed for
pthread_setname_np, no one uses vdso-transplant so it's cool with being
exploited through argv, I'll get to tmpfs_umount one day
