You can, and I will, but I think I should address this security issue with mutt
first and reroll it.  Hopefully I can get that done yet tonight, but you know
how things go....

What exactly would you like me and others to test/evaluate?  From your post
previous to the above:

"Also the code is in two distinct chunks:
1) A daemon to run under NT and 9x and provide cross-process services to
2) A security fix which Egor created the original daemon to accomplish
when passing tty handles around, and an IPC- SHM only just now -
implementation using the daemon, which has been used by me to push the
daemon limits..."

Now without IPC, are we talking about process-related things that already exist
but are implemented without a third process managing them, e.g. mmap, fork, etc?
