this fix solves the issue without any overhead of extra per thread locking and a simple lightweight retry

This has been extensively tested on a multi-proc Xeon server with the reproducers and fixes the issue. I've checked this out with a high contention of pthreads and the retry loop occurs very rarely, so the overhead of the retry is very small indeed.
