I beg to disagree with point b above: the libuv project continually
receives (and accepts) patches fixing bugs specifically for OpenBSD.
Atomic ops (compare-and-exchange) might be a harder dependency to shed
for libuv. Does the fallback onto compiler intrinsics
(__sync_val_compare_and_swap, or on GCC 4.7+,
__atomic_compare_exchange_n) not work here?
