We might also need some way of detecting duplicate txn_checkpoint()'s so
that different ra layers aren't attempting to checkpoint at the same
time like if you are using mod_dav_svn and svnserve -d at the same
time. I'm not entirely sure how svnserve works in tunnel mode, but I
suspect that many processes could be active?
