RFR: 8032901: WaitForMultipleObjects() return value not handled appropriately

[Aleksej Efimov]

Alan,
There is no test case for this issue and also the attempt to outline the 
conditions ended with no result. The report is based only on 
'WaitForMultipleObjects' code analysis and this fix is an attempt to 
make the code looks a little more correct.
