Since it is capture everything in progress, but only the kernel side of
it, why put it in the kernel? Is this absolutely required for
post-mortem debugging, or should we focus on capturing the death throes
of userspace much better (an aubcapture flight-data-recorder, plus
client annotations more akin to apitrace)?

Sell me with the bugzilla references.
