oh I didn't notice it was off-list. sorry.
Anyway, on OSX and I think Linux, Squeak/Pharo is using uuid_generate(3)/libuuid
or uuidgen on systems like Free/NetBSD

Note that the Squeak folk detected problems especially on Ubuntu
---causing segfaults when trying uuid stuff (which happens all the time with
that date back to 2010. I remember folks at ESUG being bitten by that
See discussion here:

The tricky solution there was to catch a possible segfault
and continue with image-side in this case:
