it makes no difference, you cannot sync something
which has not yet been written, and in the
examples it us very likely
a sleep .001 was by far no enuff
i still have hopes it syncs, arent pipes file fifos or something
i understand it can also be not doing anything but timings there yes

"And now for something completely different."
a sync in hope it syncs pipes makes the date | f work, but not for <( date )
f() { sync; read -t 0 ; printf $?\\n ; } ; date | f ; f <( date ) ; read -t
0 <( date ) ; printf $?\\n

This has nothing to do with shell functions. It is a simple race
condition.
