Of course, I had a look at the sources. Time hasn't been updated since
July 1996. It uses a signal handler 'resuse' that should fill-in the
resources the system uses. From a comment in time:
Systems known to fill in the average resident set size fields:
SunOS 4.1.3 (m68k and sparc)
Mt. Xinu 4.3BSD on HP9000/300 (m68k)
Ultrix 4.4 (mips)
IBM ACIS 4.3BSD (rt)
Sony NEWS-OS 4.1C (m68k)
Systems known to not fill them in:
OSF/1 1.3 (alpha)
BSD/386 1.1 (anything derived from NET-2)
NetBSD 1.0 (4.4BSD-derived)
Irix 5.2 (R4000)
Solaris 2.3
Linux 1.0
I can only assume, that numerous hackers more brilliant than me
supplied patches to Linus, but were rejected for some reason.
Or, there is a better way/program to monitor system resourses
on Linux. In any case, that's where I'd start searching after
having done 'apropos resuse', and before trying to make a port
to Linux 2.x?
In any case, this smells fishy.
