This discussion made me think of how my e-mail client works
(typically, I have five running instances of it). It somehow
keeps an eye on changes to the configuration file, so if one
instance has saved a changed configuration, the other
instances will (when they happen to feel like looking at the
configuration file) complain, and ask if I want to use the
in-memory or the disk configuration.

I don't know how trivial the implementation of this feature
is, but just keeping a copy of the time stamp of the file
with the in-memory configuration would help a bit, although
one also could use a file check-sum.
