This may have been what I was running into as well. See http://cygwin.com/ml/cygwin/2002-07/msg01894.html When doing the same compiles with in a window with tcsh running (even if bash gets invoked later on) the process numbers seem to increase much more slowly. If you do a large compile using bash as your shell, do you see process numbers creeping upward (in task manager) gradually as well?
