It's an interesting idea, the only weirdness is that one could pretty
easily tie down a lot of memory with underused instruction data and
force the filesystem cache to use a much smaller subset of memory than
it should degrading performance, it could also work against you in
the opposite direction. If solaris is able to put these pages on a
"general inactive+free queue" after some time so that pages can
migrate between the two caches it would help out some.
Interestingly enough we're trying to address a problem related to
this in FreeBSD right now, but I'm not sure the Solaris solution
is the right way to go.
