How do I sleep in Ghc?

[Lyle Kopnicky]

Here's a POSIX implementation of a sleep function in C, as found in the 
book "Advanced Programming in the UNIX Environment":

    http://www.yendor.com/programming/unix/apue/lib.svr4/sleep.c

AFAIK, all the GHC platforms, including Windows, are POSIX compliant.  
You could compile this code separately and call it via the FFI.  If it 
doesn't work on Windows, you could instead call:

Win32::Sleep(TIME) 

    [CORE] Pauses for TIME milliseconds. The timeslices are made
    available to other processes and threads.

Hope that helps,
Lyle Kopnicky

BTW, you have a very interesting disclaimer in your message.  I hope I 
will not go to jail for reading it.
