It's worth mentioning somewhere in the instructions that "make -j"
doesn't work when building openjdk. The actual parallelism is
supposed to be controlled by HOTSPOT_BUILD_JOBS, but it doesn't seem
to be very effective. On a dual-processor box with
HOTSPOT_BUILD_JOBS=4 I get:
Control build finished: 07-05-09 13:00

0inputs+0outputs (1002major+40812683minor)pagefaults 0swaps
which is not bad, but it would be nice to increase the parallalism.
