Valgrind patch for Gnome2 debugging

[Cody Russell <bratsche gnome org>]

Hi all,

Here is a patch for the latest Valgrind snapshot.  It adds support for
two new syscalls, __NR_sched_get_priority_min and __NR_setpriority. 
This was sufficient to get it to work with Gtk and Gnome 2.0
applications.  I've sent the patch to the author of Valgrind, but
Kjartan suggested I send it to GNOME mailing lists in the mean time for
people interested.

For those not familiar with Valgrind, as I wasn't until yesterday, check
it out at http://developer.kde.org/~sewardj/ ..it's definitely very
useful.
