Additional context

ran into an issue with examples/smbserver.py trying to list large directories,

returning more than 550 files causes samba to hit an assert and crash (libsmb/cli_smb2_fnum.c(1497): response->length > state->offset), and win10 will freeze for a sec before it shows a generic <unc> is not accessible error

depending on filename-lengths etc, had to clamp the number of files to return from findFirst2 down to like 300 or so
