Hi
        this version contains a bug-fix to two test and a new test for
        ipc operations.

Memory test suite v0.0.2
------------------------

This is the second version.

This intends to be a set of programs to test the memory management
system.  I am releasing this version with the idea of gather more
programs for the suite.  If you have some program to test the system,
please send it to me (quintela@fi.udc.es).

If you found values/combinations of tests for what the system
crash/Oops/whatever please report it to me.  Then I can include it in
the tests and the people who tune the MM system can test it next time.

This version has added support for ipc001 test and solved a couple of
bugs in mmap* tests.

Any comments/suggestions/code are welcome.

Thanks for your time,
        Juan Quintela

I've just been trying this package out on a NetWinder, and I've just
deadlocked 2.3.99-pre6 - I've got 0KB memory free!  I changed misc_lib.h
to reflect the amount of RAM I have in this machine (32MB).

I ran ./mmap002 twice - the first time it got a bus error.  The second
time it didn't even make it to the first msync() call.

Here is the mem and state info.  If there's anything other info you want,
let me know - its extremely easy to cause this.
