Do we need to? The problem is in essence since we rely on free
resources, sometimes some heavy lifts take longer.  That's what this
flag is for.

I'm sure we could make sandbox take too long to start as well, if enough
other things are going on with the system.  And sandbox has its own set
of super frustrating issues instead, so I don't think this is a great
argument to have right here (I have to run it in docker, to get around
some application version requirements and exclude event_dump, bootmgr,
abootimg and gpt tests, which could otherwise run, but fail for me).
