We would not wait on the lock if force=false, which would do
nowait=true. And !force reads the same to me as force=false.
Anyway, I am OK to remove this part. That seems to confuse you, so
you may not be the only one who would read this comment.
Another idea would be to do like in pgstat.c by adding the following
line, then use "nowait" to call each sub-function:
nowait = !force;
pgstat_flush_wal(nowait);
pgstat_flush_io(nowait);
