V3: SPARC bug and tree freeze

[Robert Dewar]

<<We already run thousands of tests before checkin, including C, C++,
Fortran, and library tests.  That already takes hours for many people;
glibc takes about that same amount of time to build, even on a fast
machine.

But couldn't the needed testing be distributed on several machines
with appropriate robots, and run in parallel. I know I am coming
late to this discussion, but it does not seem workable for the tree
to get this broken to me.

I must say I am a bit surprised that glibc should take hours to build
on a fast machine -- is that really the case -- gigaherz processors
chew through stuff pretty quickly :-)
