who said that to you? Gstat access db file directly only with -h
option, and with other options it does not access directly the
database file and does not need any "exclusive access" or something
to the database, even with -h.

not at all. run gstat -a -r or gstat -h whenever you wish, while users are working.
The only effect of gstat -r will be that it will read the whole
database, and for the big file (10, 20, etc gigabytes) it can take
some time, and with poor storage it can affect performance (not so
much).
