hi, I have simplified the test case a bit. Wrote 2 .py files, one I get slow emacs, the other I get normal(smooth) emacs: $cat slow.py #!/bin/python import os os.close(0) os.close(1) os.close(2) #must make sure X server is running already, or else this doesn't show #anything, even no -nw version of emacs. my /bin/emacs is alternative to #/usr/bin/emacs-X11 os.system("emacs -q") $cat fast.py #!/bin/python import os os.system("emacs -q") (And my original problem is `run emacs' in cygwin.bat console will cause emacs slow, and I observed there's only one fd (socket to X) open for the emacs process started this way; no stdin/out/err). -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
