The THIRD_PARTY_NSYNC and LIBC_THREAD packages include source code
from *NSYNC. Here's the latest upstream synchronization point:

NSYNC uses the Apache 2.0 license. We made the following local changes:
Write custom nsync_malloc_() so malloc() can use *NSYNC.
Rewrite futex() wrapper to support old Linux kernels and OpenBSD.
Normalize sources to Cosmopolitan style conventions; *NSYNC upstream
supports dozens of compilers and operating systems, at compile-time.
Since Cosmo solves portability at runtime instead, most of the build
config toil has been removed, in order to help the NSYNC source code
be more readable and hackable.
