Not really. You want hgsubversion at googlegroups.

Your /machine/ crashes? On the level of a kernel panic or something?
I'd guess you have bad RAM or something in that case, I don't see how
a user-space app like hgsubversion could have anything to do with
crashing your hardware.

Depends on the repo size. Large repos take a long long time to pull.

hg log --debug, or (slightly better) hg log --template '{node|short} = {svnrev}'
