I saw some similar goofiness at one point, but do not recall whether it
was related to cryptography. I am interested in it and the SSL classes.
I managed to install same at one point, but it is no longer clear how I
did it. Mining the change log of the most recent image where it works
(I have one) and/or searching my email exchanges with Ron might help.
The idea being to figure out when it worked and then look for special
instructions that I might have followed.
Gary, it would be nice to have your mutex fix in Pharo. One of the
first things I would hope to get working on Pharo is very multi-process
oriented, and a reliable #adddeferredUIMessage: would be most helpful.

That is normally a symptom of something updating the World morphs in a
non-UI process.
Morphs should only be changed from the UI process otherwise all kind of
inconsistencies can happen.
WorldState addDeferredUIMessage: can be used top safely perform actions
but,
for some applications, finer control is needed.
We have developed Squeak applications that are of necessity
multi-process
driven and were forced to modify WorldState to allow (mutex based)
synchronisation with the event loop, thus avoiding the issues.
Regards, Gary.
