There were objections against modifying the vfd api only for this
replication-related use-case. Having a new API will require all the
changes required to enable the virtual FDs feature that we need from
vfd. If nothing works out from the FILE_SHARE_DELETE thing, I am
thinking, we can use VFD, plus we can keep track of per-subtransaction
vfd handles, and do something similar to AtEOSubXact_Files().
