Log Message:
Step 1 of my (not yet finished/successful) attempt to fix
[ 1976341 ] XQ: leftovers after deleting document
https://sourceforge.net/tracker/index.php?func=detail&aid=1976341&group_id=56967&atid=482468
Fixed and simplified the implementation of "pf_logmanager()".
The strategy should still be the same, i.e.,
flush the log at most every 5 minutes,
and only if there have been at least 100000 changes since the last flush;
check every 30 seconds, whether a flush is required.
