the retry loop in svn_io_file_lock2()

Why does svn_io_file_lock2() have a retry loop?

The reason given in the code is that some consumer of libsvn_fs wants to run
a critical section while holding a lock in each of two FSFS filesystems. In
that case, why isn't the fix just to tell the consumer to, when wanting to
lock N filesystems, to always lock them in a well-defined order?

Concretely: sort the filesystems by their UUID lexicographically.
