Why do you want to say that?
How is that any different from bugs in any other part of the system?
I agree with Simon that saying that creates FUD in the minds of the
users, and I don't think we should do that unless there is a very strong
justification for it.  So far I haven't seen any such justification.

Anyway, it doesn't belong in the NEWS file.  Hence the following patch.

Estimated hours taken: 0.5
Branches: main, release

NEWS:
	Back out Ralph's change, as per discussion on mercury-reviews
	mailing list: this text does not belong in the NEWS file,
	and I don't think it should go in the BUGS file either.

 Changes to the Mercury compiler:
 
-* Due to personnel changes and semantic problems in the design of
-  POSIX threads and problems in the implementations thereof that we have tried,
-  we cannot guarantee that we will be able to fix low-level concurrency bugs in
-  .par grades.
-
 * We have added optional support for a new type-accurate garbage collector
   as an alternative to using the Boehm et al conservative collector.
