If you're willing to touch my nasty Python - that'd be very welcome! :)
Right now I put this in the configs:
[vm]
exports=KSFT_MACHINE_SLOW=yes
We can leave the support for adding exports in place, but we should add
a new config option like
[vm]
slowdown=2
(exact name up for debate), if it's present generate the
KSFT_MACHINE_SLOW=yes export automatically, without the explicit entry
in the config. And add the export for the timeout matching the logic
you propose (but in Python).
FWIW here's the configs we currently use:
$ cat remote.config
