[Spice-devel] [RFC PATCH spice-server v4 21/22] WIP: Try to reduce delay

[Jonathon Jongsma]

A description of the problem you're trying to solve here would help me
evaluate this patch. You say that it's "WIP" and "hacky", so I assume
that you don't intend this to be the actual solution, but without some
discussion of the behavior before and after this patch, it's hard to
comment intelligently.
