Define extended period of time.  I do builds of my project dozens of
times a day, they take about 5 minutes using 100% cpu of all four cores
for that time period.  Sometimes I do full builds, which uses 100% for
about 25 minutes.  Never the slightest problem.  It currently has a 20
day uptime, but it would be 30 days if not for the fact that I had to
power it down to mount it in a case.  A sad day that was. ~:^)

I should point out that the full build builds from scratch, gcc, glibc,
libstc++, a whole bunch of java extension libs, a 2.4 kernel, and our
software, in that 25 minutes.  Does this AMD64 stuff rock or what?  The
dual xeon build server takes 2 hours to do the same work.
