Alan,

Re morphic lockups, I have no sense of whether eToys contains any bugs
that would lead to it, but I definitely had a flawed morphic system, and
found it quite challenging to debug.  It finally fell after some VM
hacking, in which I took existing pieces and wired them to a hijacked
menu item.  In particular, I modified the Dump Call Stack command to
dump callstacks for all Processes that were waiting on semaphores,
instead of just the active Process.  I reported it at the time, per the
license agreement.  It is a simple change that would help in cases like
this, if only to rule out a problem, and possibly (as in my case) to
point to a solution when there is a problem.
