That's what I thought - the problem seems to be with the interaction between
ghci threads (there are four OS threads running on my machine).  I read the
conc-ffi paper by Simon Marlow, Simon Peyton-Jones and Wolfgang Thaller and
whilst that explained the situation regarding bound threads (and indeed how
to ensure running a bunch of actions within the same thread context - which
gave me some hope), I am still no wiser as to what is going on here and how
it can be fixed. It at all.
