RFR 7140929: NotSerializableNotifTest.java fails intermittently

[Jaroslav Bachorik]

Hi,

please, review the following small test change:

Issue:  https://bugs.openjdk.java.net/browse/JDK-7140929
Webrev: http://cr.openjdk.java.net/~jbachorik/7140929/webrev.00

The test fails intermittently, mostly when it is run with -Xcomp option. 
The failure is due to fixed timeout used in the test when waiting for 
the notifications arrival. Tests of such slow configurations are run 
with "timeoutfactor" set but the NotSerializableNotifTest does not 
respect the timeoutfactor.

The patch allows the test to reflect the provided "timeoutfactor" and 
therefore successfully pass even when -Xcomp is used.

Thanks,

-JB-
