When start a new Windows process, the system attempt to recycle a previously
used PID, so the maximam PID in the system is low. But when I invoke a
command in Cygwin, the PID of new process always increase. It may not be a
problem as long as the maximam PID doesn't exceed the limit, but
unfortunately it will. As I discovered, my Win2000 Professional system's PID
limit is a little more than 17000, many configure script I have run, such as
mysql and net-snmp's, aborted because unsuccessfully fork().

Why does Cygwin's fork() behave unlike native Windows, since it is based on
CreateProcess()(http://www.cygwin.com/faq/faq_3.html#SEC77)? I'v searched a
post on why use two types of
PID(http://www.cygwin.com/ml/cygwin/2003-10/msg00139.html), does it matter?
