25 # note: starting emacs server can hang due to errors in init files
26 # which don't cause problems for non-server emacs. And things
27 # that aren't errors can cause hang too, like when I added gnus
30 # I was experimenting with running
31 # under gdb always to diagnose any hangs/crashes
32 # and it won't work due to a gdb crash:
33 # gdb -ex="set follow-fork-mode child" -ex=r -ex=quit --args emacsclient -nc
34 # -n = --no-wait, go into background
35 # -c = create new frame instead of reusing the current frame
36 # -a = alternate editor, empty string makes it start emacs daemon.
37 # This is also set via env variable, but that doesn't propagate everywhere.
