(** Thread-compatible system calls.

This module reimplements some of the functions from [Unix]

so that they only block the calling thread, not all threads
|
|
in the program, if they cannot complete immediately.
|
|
See the documentation of the {!Unix} module for more
|
|
precise descriptions of the functions below. *)
