I don't think it is anything to do with processes (there was IMAP SSL,
aspell and shell when I was having the problem) it looks to me as if the
getmail/savemail command is doing lots of elisp commands and taking
30+sec to return to the user. It's the foreground that is the issue
.. my session locks up (but C-g'able) until the get/save returns.

It is looking likely that this is a problem with the latest emacs build
rather than vm - I'm now trying running on a non-latest build and *so far* I
can't see the problem. I'll give it to the end of the day and if the bug
doesn't reappear (so then it would appear to be changes in the emacs src
trunk) I'll then need to try to get some test case together that I can
get an emacs bug report together and I'll try profiling it when the bug
is active.
