recv() returns the number of bytes actually read, the passed in buffer
only limits the upper bound of how much it will read. If 3 bytes are
what's available when you call recv(), it will return immediately
having given you those 3 bytes. It only blocks if no data is currently
available at all (and the socket isn't in non-blocking mode)

Writing to the same socket from multiple threads is perfectly valid,
as with any other file descriptor.
