Thread and Unix select

Thread and Unix select

[Alex Baretta]

What are the differences between Unix.select and Thread.select? Is it 
safe to use the former in a multithreaded program?

Without looking at the implementation, I would guess that a
Unix.select with a non-zero timeout would cause the whole process to
block - whereas an equivalent call to Thread.select would only cause
the calling thread to block.

Once upon a time, this was the intention of Thread.select. In current
ocaml, one can also call Unix.select, and only the calling thread is
blocked.
