This is just a short note for everyone (anyone?) following the DTrace sources
via cvsup10.freebsd.org.

There was short period of time over the last day or so where the buildworld
on i386 would have created a boot loader that was broken.

I doubt that anyone would have been bitten by this because the kernel
build was broken for a while too. Oops.

This happened while the sun4v support was being merged into the DTrace
project.

Thanks to Sun Microsystems for providing an extra  Sun Fire T2000 server for
FreeBSD development. 32 logical cpus, 32 GB of memory, 4 gigE ports, 4 USB.
Watching a make -j32 buildworld with 32 cpus all running at close to
100% is _really_ impressive!

See: <http://www.sun.com/servers/coolthreads/t2000/test/overview_e.jsp?name=E>

Expect to see DTrace built into FreeBSD/sun4v over the comming weeks.

(Note: As part of the sun4v import, support for libpthread and KSE has been disabled.)
