[M3devel] cvsup crash

Very little is known. I don't think we should be so quick to assume a regression in cm3.
For example, cvsup only recently was ever made to work with non-userthreads.
And this version has seen extremely little use. Perhaps it never actually worked with non-user threads.
It previously depended on all threads surviving fork().
Bugs could easily be in cvsup itself.
As well, don't we know that Trestle has forever had several race conditions?
  Having recently fixed a few?
 
It's been my experience that the less something is used, the more bugs it has..
Modula-3 * cvsup + trestle...

It is certainly worth

Given how poor cvs is in the first place, and how many promising alternatives there are now,
it seems a waste to invest in learning to use cvsup, or spending much time debugging it and fixing it.
But maybe we'll get it working.



It is certainly worth fixing bugs exposed by cvsup.  It used to run.  Why does it not run now?  Has there been regression in the CM3 implementation?
