RFR 9: 8086278 : java/lang/ProcessHandle/TreeTest.java failed - ProcessReaper StackOverflowException

[Martin Buchholz]

If you're actually seeing faiures with 32k, then 48k is too
conservative.  I suggest 128k.

I tried once to increase the limit to 64k, but without a failing test
it didn't get any support.

The presence of native thread local variables is the biggest reason
for blowing the stack; no limit is actually safe!  That's a deep
hotspot/glibc problem.
