Walter, I'm not sure I'm understanding this, but I did a test with mtcomplexshare.prg and I see that nGlobalCounter is protected by a mutex lock/unlock sequence.
If I remove those mutex calls on OS/2 with GCC at the end the result shows big
differences.
--------8<----------------
Thread 1 - LocalCounter= 5449444
Thread 2 - LocalCounter= 5469999
Total 10919443
GlobalCounter= 6345520
Difference 4573923
(E:\repos2\xharbour\tests)
-------->8----------------
See attachment.
