After the patch that I posted yesterday, we finally get to the real
problem.  I've tried to address it by allowing a hashtable to have a
mutex associated with it - resulting in the patch below.  But
unfortunately it's still not good; a sample run of test-define-race
gives:

#<module (guile) 40376f00>
#<directory (guile-user) 40379680>
ERROR: ERROR: Unbound variable: x1-100499
Unbound variable: define
ERROR: Unbound variable: x4-100596
ERROR: Unbound variable: define
ERROR: Unbound variable: define
ERROR: Unbound variable: define
guile-define test case: good-bye!
test-define-race: 2 error(s)
FAIL: test-define-race

I'm off to sleep now, so I thought I'd post what I've done in case
others have thoughts on it or can see something wrong.

Regards,
        Neil
