Per-connection is easy: 'man ulimit'
Across all connections is possible if your system supports per-user
limits (in addition to per-process) but otherwise all the bookkeeping
would have to be done in the server, kept in shared memory and managed
with a semaphore. Somehow I doubt you'd get that patch accepted. :)
