Could you please clarify an issue here? (Sorry, it seems, I wronged to 
``run'' in the previous posts.)

In a Windows command prompt (being somewhere on C:) I put the line
        \cygwin\bin\run -p /usr/bin sleep -wait 5
into a file ``dosleep.bat''. Executing that BAT-script (w/o any wrapper), it 
*does* sleep. Typing that very line directly at the prompt lets ``run'' 
return immediately, though. Can you confirm this behaviour?

Another possibility would be an option ``-n'' to specify the number of

I'd volunteer for that. How/where do I upload?
