Yes.  We've definitely seen this too.  For example, our regression
tests generate many very short spread sessions.  We have re-tries in
place to avoid failures when the disconnect isn't processed quickly
enough.  (This even happens with a single client and a single daemon.)

I don't have infinite patience <wink>, but I did wait for 5 minutes.
