>From the patch description:


It seems we are calling tdb_reopen_all for two reasons:

The first reason is to make sure we get a new seek pointer.  If the

has a native pread and pwrite (libreplace didn't replace them), we don't

need a new seek pointer.


The second reason has to do with the TDB_CLEAR_IF_FIRST flag.  It
appears safe

to not have to reopen in this case since a child process will never be

first to open a tdb.  We will pay a penality if the child decides to
reopen a

tdb, but looking at the usages of tdb_reopen, that seems rare.
