Make Rust work correctly with callgrind / kcachegrind

[brson]

I love this tool but it reports all of the interesting function calls happening in a big cycle, making it useless. I imagine this is because of context switching. Callgrind has a way to ignore some functions, supposedly allowing cycles to be broken, but I haven't figured out how to do it.

Nominating for milestone 4, well-covered

just a bug, removing milestone/nomination.

Bug triage; still on the wishlist.

Triage: still appears to be an issue with code that uses tasks, but (from my brief testing) is fine in code that doesn't spawn any new ones.

I looked into valgrind's docs etc but haven't been able to discern anything that would be useful here. Furthermore it only manifests with green tasks. I couldn't find any docs about how GNU Pth (another userland threading library) handles this if at all. I assume it's plain not possible.

Since it works with libnative, this isn't a big deal now.

Agree
