I've started a conversation on the xorg-devel mailing list[1], and I'll
follow up directly in irc with Adam and/or Keith if I don't get any answers.

Could I ask that my last patch be committed regardless?  You really
cannot use Xspice if the large ping results in an EAGAIN result; the
client just hangs.

Cheers,

Jeremy
