Re: (ITS#5451) syncprov_checkpoint deadlock bugfix?



Does this help?  From my fiddling with ITS#5340 (REP_ENTRY_MODIFIABLE).
I do not understand syncprov's handling of REP_ENTRY_MUSTRELEASE though.
(For one thing it seems to assume that REP_ENTRY_MUSTRELEASE is set if
and only if rs.sr_entry->e_private != NULL.  Which is possibly true with
back-bdb but seems a shaky assumption in general.)
