I tried this with normal developer box type load on a slow box ie;

2x 400MHz 512MB source/build fs' on UW2 SCSI
kernel: 2.5.72-mm3

2x make -j2 bzImage
bk pull (linux-2.5 repo)
cvs import of 2.5 tree
navigating bk revtool (this normally causes pauses)
read disk benchmark just to thrash IDE about a bit ;)

Still a few MP3 pauses (due to bk revtool mainly) but mouse/keyboard
response was good, there is however a vast improvement over 2.5.73
stock (2-5s pauses with no keyboard/mouse response) for my particular
workload.
