Definitely not a near-term concern for tconsole, but it'd be neat if we could eventually configure it to take advantage of multiple cores and get tests done even faster.
Shouldn't be too hard if we just fork for each test suite and make sure that the number doesn't exceed the number of cores on the system.
Should we set a milestone on this? 2.0, maybe?
Let's just let it sit for a bit - I don't see it being so big of a change that it requires a major version bump, and it may be something we can hack together pretty quickly.
