share/man/man9 : lim_cur.9
Log message:
Make resource limit access MP-safe. So far, the copy-on-write sharing
of resource limit structs has been done between processes. By applying
copy-on-write also between threads, threads can read rlimits in
a nearly lock-free manner.
Inspired by code in DragonFly BSD and FreeBSD.
OK mpi@, agreement from jmatthew@ and anton@
