ntacl sysvolreset can take a long time

Depending on the amount of data in the sysvol directory, the samba-tool
ntacl sysvol reset consumes a lot of time.
But there is an additional cause for highly increased duration of the
process. In a small setup it takes round about half a minute when Samba
is running and just 4 seconds when Samba is not running.

One distinct difference between samba is running and not running is the
amount of fcntl() calls.

I count 1722462 when samba is up, but just 147214 if samba is not
running, which is a large difference. Maybe somebody have some ideas how
we can improve this :-)
