Queue depths.  Varying paths.  IIRC, 802.3ad DOES NOT allow round
robin distribution; it uses hashes.  Sure, hashed distribution
isn't perfect.  But it's better than "perfect" distribution with
added latency and/or retransmits out the wazoo.

You don't even need varying paths to create a desynch, all you need is
varying size packets.

Quite true.  My list wasn't meant to be all-inclusive... bad
wording on my part.
