As I'm sure I've pointed out before, and Kate certainly has, I haven't
seen Solaris lock solid when it runs low on RAM.
I personally don't care if OS Foo overcommits, undercommits, or has
unresolved commitment issues. I just want to be sure it's not going
to lock up if it runs out of RAM at 3am. I've seen Linux do it too
many times to trust it. I've seen Linux fans make too many excuses for
its egregiously brokenness to trust their judgement.

Solaris runs happily swapless out of the box. Solaris, out of the box,
doesn't lock up when it runs out of RAM. Tru64 I can't speak for.
