RFR(S) 7195597 [TESTBUG] ThreadStateTest gets different results with -Xcomp

[Morris Meyer]

Folks,

The ThreadStateTest has exhibited sporadic and rare timing issues with 
the -Xcomp flag in some settings.  I've added workaround code to the 
test to detect the '-Xcomp' flag and lengthen the retry timeout accordingly.

This has been tested through the Sfbay JPRT.
