[11u] RFR 8229020: Failure on CPUs allowing loads reordering: assert(_tasks[t] == 1) failed: What else?

Hi,

Please review this one line patch.

It removes a paranoid assertion, that may trigger false alarm on weak 
memory systems.

The original patch does not apply cleanly, mainly just due to line shifts.
