New worker threads are spawned on as needed. You'll need as many of them as you have simultaneously-blocked foreign calls. If you have 2000 simultaneously-blocked foreign calls, you'll need 2000 OS threads to support them, which probably won't work.

Does the RTS use select() to multiplex network IO instead of spawning threads?

Yes. Cheers, Simon
