How long a hang have you observed? Since you brought down a client,
the MDS needs to wait through a full time-out period before letting
other people do things (it's giving the previous client a chance to
claim some state). The default looks to be 45 seconds right now.

But the patch shouldn't have changed that behavior in any way; so if
it's actually different behavior in testing then we just
broke...something else, somehow...
