I've been skipping this test for a while on my weaker systems,
but this makes it automated so it avoids triggering a swap storm
for Linux users less familiar with the test suite.

I think this only affects Linux which defaults to overcommit. Asking
users to disable overcommit is unreasonable, so I figure this is the
best way...

I'm not against that check, but we may enable that test only on 64bit Windows, since it is nearly impossible to reproduce on other platforms, because of memory usage.

OK, can you add the 64-bit Windows check instead?
I do not know the proper platform checks for those, there are so many.
It think *BSD folks on smaller machines may appreciate it more.
Thanks.

test_string.rb: enable huge test only on possible platforms

• test/ruby/test_string.rb (test_LSHIFT_neary_long_max): enable
  only on platforms where string size range is smaller than memory
  space. this test does not make sense but just wastes memory and
  time on other platforms, as it is hardly possible that a string
  size becomes neary LONG_MAX if long size equals pointer size.
