[issue22964] dbm.open(..., "x")

[Serhiy Storchaka]

Agree with Batuhan. There are three dbm implementations in the stdlib: dumb, ndbm and gnu. It may be possible to implement the "x" flag in the former two, but gdbm_open() does not support it.

Since by default the implementation is chosen automatically in dbm.open(), I do not think it is practically to implement a flag which do not work with all implementations.
