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).
