Such an API would create the risk that Subversion on one platform would
be using plain file locking, and on another platform would be using
POSIX-type file locking, on the same working copy in a networked file
store.

If we were planning for 1.0 now, I think it would be reasonable to just
use apr_file_lock(). We do that for FSFS (for commits, and pre-1.3 for
all operations) and it still works okay in most network filesystem
setups. But I'm not sure it's reasonable to make svn working copies
stop working in the few exceptional cases during the 1.x line.
