Attached patch should workaround this. The main problem with it is that
Dovecot doesn't die very easily after this. You have to kill all the
processes manually. I'll probably have to add yet another pipe just for

But I wonder if this could be considered a kernel bug too? I think I'll
write a small test program and see what lkml thinks about it. Oh, and
seeing if other operating systems handle it better would be interesting

BTW. I actually considered this already last week but then I thought it
can't be it since v1.2 did the same thing. But no, v1.2 doesn't really
do the same thing.
