RFR: 8034944: (process) Improve subprocess handling on Solaris

[Martin Buchholz]

OK, latest webrev looks much smaller, and appears to have only a port of
changes from my changes to Linux from a few years ago.  (please confirm).
 If so, Looks Good To Me.

While looking at this, I think bumping the thread stack size by a factor of
2 (32k => 64k) seems timely, since native stack requirements (native sizes,
alignments and overhead) seem to increase over time.  But I'd put that into
a separate change.
