We'll need to make stack capturing thread-safe. This probably means to have a dedicated mutex & locking around stack capture invocations & data access.

Looking over this, we already mostly protect the shared data in `KeyedStackCapturer`. KeyedStackCapturer::Capture() doesn't protect all the data accesses yet though.

Hi Georg! I triggered a try build for this patch here: https://treeherder.mozilla.org/#/jobs?repo=try&revision=176159b91df2&selectedJob=74796902 Some tests failed but they seem unrelated. For some reason I cannot re-trigger the jobs and cannot login either with LDAP or mozillian accounts. Can you re-trigger the tests that failed?

Those test failures look unrelated, i've triggered autoland.

Is this something that should go in 53 or is it going to ride the trains?

Not sure about that, but :gfritzsche should know what is best.

There is no code shipping in 53 that uses it, so there is no uplift needed.
