I secretly demoed this today in a live demo tutorial demonstrating the
Gecko Profiler over Vidyo on the latest Win64 Nightly. Thanks for
improving things so much, David!

Hi,
The Gecko Profiler used to be notoriously unstable on 64-bit Windows.
(If you're curious: it's mostly because the unwinding rules for Win64
require the system libraries to do a lot of synchronization, which our
stack walker would often call in ways that could deadlock.)
Ever since the last Quantum Flow work week, I've been working on
fixing these issues. As of this week's nightlies, all of the hangs
that have been reported to me are resolved fixed. There might be some
rare corner cases still remaining, but I'm confident that the most
frequent problems have been addressed.
So my ask is: if you've previously been deterred from using the
profiler on Win64 builds, please give it another try! Flag me on any
issues you find and/or mark them blocking bug 1366030. I will treat
these bugs with high priority since I want to keep Quantum activities
unblocked.
Thanks!
