Exactly.

This doesn't really affect the RAM disk question, but
I'ld like to correct an error in my previous posting
about the sticky bit for executables.

Back in the old days when processes were swapped in & out
in their entirety, the text segment of sticky executables
would remain in the contiguous swap space to avoid seeking
all over the disk when starting the next invocation.

I incorrectly posted that the text segment remained in core.

So the sticky bit for executables probably is irrelevant
to demand paged virtual memory systems and is merely
a harmless historical oddity.

Thanks to eric@skatter.usask.ca (Eric Norum) for straightening
out my memories of a twisted past.
