I would post a bug report. I know linkedin has over 10k nodes with saltstack. Thomas was there tuning it so I'm sure it should work.

its something they know about. The current workaround is multiple masters, which isn't entirely practical

Wikimedia runs 1,000+ nodes on a really small box. No need for multiple masters. Just increase your worker threads.
