That certainly helps in the case that I forget to C-d in the IDL
session. There are two other situations that I regularly experience
that you can perhaps help with.
1) Until I fixed a video card driver issue, iTool was crashing my
xserver which caused a loss to changes in the IDL comint history. I
suppose this could happen again.
2) I often leave an emacs/IDL open on my work computer. When I get
home, I may do a bit more work by running emacs, etc across X; also a
situation where I don't have access to the last comint history
changes. This is not a big deal, just a "nice to have".
For situation 2), is it possible to issue a HUP-like signal from a
remote shell to kill the emacs running on my work computer in a way
which invokes your save comint code above?
Thanks!
