[Spice-devel] [server PATCH 2/3] replay: learn how to skip the first N (slow) commands

[Uri Lublin]

Note that the commands are executed by spice-server.
The "skip" is only done on the "sleep" part of the
"slow" command-line option.

This is helpful to run quickly through uninsteresting commands
in a beginning of a recorded file and going slowly when
interesting parts appear
