I will have to investigate this further. Which distributions are
you referring to?<br><br>
This would be a crying shame! I would hardly think it would<br>
make sense to change the use of the sticky bit. It's intent<br>
and impact was indeed quite real. This would be more like<br>
MS Office programming, not an O.S. Fat cats get at it?<br><br>
If every invocation of Linux is copied to swap, they have<br>
regressed to days prior to AT&T Unix System V.3. Why<br>
would they do this? Sell more Ram? Enjoy waiting while<br>
the same text pages from the same executable are loaded<br>
to swap?<br><br>
On my RH Enterprise 3.0. Fresh boot, loading a utility I<br>
developed a ways back, loads itself, then recursively calls<br>
subroutines, and allocates normal heap and stack (by default,<br>
it can be set, and has some Shared Memory options as well),<br>
from my olden days, shows on repeated load, the amount of<br>
virtual memory utilization did not increase, nor did the swap<br>
space allocated.<br><br>
(Commercial distributions we run on our IBM platforms, even<br>
up to the time they switched from AIX acted in this manner...<br>
I can't say it is this way for all distributions. However if this
is<br>
the case, than IMPO, Linux just became an inferior Cheap<br>
Unix. I wouldn't mind... if it not been removed!<br><br>
I have seen your writing before, and indeed I believe you, and<br>
the quote, I just "cant' believe" the quote. Are
they referring<br>
to perhaps a "regular" non-executable file (I refer to in
Kernel<br>
speak as text, hope that did not confuse anyone..)... When I
say<br>
"Text pages", I am referring to the "executable code"
that is either<br>
static, or dynamic through a shared "reentrant"
library....<br><br>
I will be able to check RH 9.0, Mandrake 10.1, (which I just<br>
received an update on) SuSe 7.3, and Slackware 7.1<br>
This would really bum me out Steve...<br>
<br>
With Regards<br><br>
Mark<br><br>
ps. I was rushing to catch a train... didn't see the long
tail...<br><br>
