I tried your example on my quad-core Windows XP machine and don't see the
increased memory usage over time.  On your machine it's likely to be BLODA. 
Which BLODA?  We can't tell because you haven't provided the basic debugging
information needed to try to identify it.  As mentioned earlier in this thread,
that would be the output of 'cygcheck -svr', *attached* not appended to your
next post on this topic.

<http://cygwin.com/faq/faq.using.html#faq.using.bloda> is the list of known
dodgy apps (what we call BLODA).  Have you looked at that list to see if you're
running any of those apps on your machine?

Your first post mentioned that the increased memory stayed "used" even when you
closed the Cygwin window.  That is a hallmark of BLODA.  Corinna explained why
Cygwin can't accomplish that feat elsewhere in this thread.

One has to start somewhere.  There is no magic "fix it" button for this issue. 
Please provide the basic debugging info and we'll see what we can do.
Respectfully,

..mark
