Hm, that's improbable. When I was still running the Windows tests, on a
ramdisk, I got a very substantial speedup. I did have to put the whole
tree on ramdisk, though, including source and binaries. Which makes for
a fairly large ramdisk, and you have to enable test cleanup; several
gigs of RAM does help here.

'net. No, Windows is not a comfortable development platform.)
