Request for review correction of regression test compiler/6857159/Test6857159

[Pavel Tisnovsky]

Hi all,

I prepared correction for regression test compiler/6857159/Test6857159.
This test (i.e. original version) usually runs fine on my test machine,
but it sometimes fails due to timeout which is set to 240 seconds (2
minutes) for all reg.tests by default.

My test machine is quite powerfull (Two Quad-Core AMD Opteron Processor
2350 = it's possible to run 8 threads concurrently, 8 GB memory), but
the test takes about 260 seconds on average. So I prepared two variants
of correction:

http://cr.openjdk.java.net/~ptisnovs/Test6857159correction1/
- the timeout is increased to ten minutes (600 seconds)

http://cr.openjdk.java.net/~ptisnovs/Test6857159correction2/
- the number of iterations is decreased to one half of original value
(which IMHO does not change the authenticity of this test but I may be
wrong of course)

Can anybody please review these corrections and decide which correction
(if any :) is better?

Thank you in advance,
Pavel T.
