05:31 brrt2 it is not very rich in detail unfortunately
05:32 brrt2 one of the thingw i like about moar is that the responsibilities of spesh and the jit are cleanly separated

05:50 nwc10 Yay \o/

10:55 jnthn timotimo: The threads form a linked list hanging off instance
10:56 jnthn timotimo: Linked list 'cus it makes handling thread death easier than an array :)
10:56 timotimo ah!
10:56 timotimo well teaches me for just looking into Instance
10:56 timotimo is that a sensible way to try to get profile data from all threads?
10:56 timotimo or should i also look into marking the thread stolen or something like that?
10:57 jnthn I think all threads *do* recording profiling data
10:57 timotimo yes, they do record
10:57 jnthn Or at least, can
10:58 timotimo is it safe to just grab the data while the threads are potentially still running, though? :)
10:59 jnthn Hmm
10:59 jnthn Good question :)
11:00 jnthn Potentially not :)
11:00 jnthn Also those threads may end up with "unfinished business" in their call stacks
11:00 jnthn Which may throw off timings etc.
