I dunno about fsync(), but Linux has the opposite: cork and uncork.
TCP_CORK completely disables further writes of less-than-full frames.
The motivation is an app like sendfile(): squirt out "metadata"
(HTTP mime headers) first, then send the file data in full frames
(Or 8k chunks on jumbo ethernet, I guess).
