Reduce memoizer wait to 0 (Fix #10337)

For relatively fast setId alls, no bfmemo file
was being produced. Lowering this value to zero
shaved off 1/3 of the setId time, though, even
for fast files.

This should also prevent discrepancies when the
system is underload: now a memo file will always
be produced.
