svn update select(2)

Hi hackers,

We've got a customer that needs to move some data out of SVN and we wrote a
tool for them to do so.

Unfortunately, that tool is slow because svn update seems to artificially
slow itself down, I've straced it and at the end there is a select() that
waits until one second has passed by. I'm guessing there is some sort of
transaction log that doesn't want to be updated more often than that?

Before I waste more time (spent a half hour in the sources this morning
between dealing with kids), is there a flag to turn this off? With it
on it makes SVN appear to be 12x slower than BK and I know it's not that
slow.

Thanks,
