Hi, I'm trying to catch panics in some code with Flume: ```rust pub fn add_allocation(&self, address: usize, size: usize) { // simplified from real code. catch_unwind(|| { self.sender.send( AddAllocationCommand {...

Disconnecting a channel should, perhaps, drop unreceived messages

Flameprof is failing to parse profile output

Hi, I'd like to tell people about flameprof in talk I'm giving, but it's failing for me: ``` $ python -m cProfile -o out.prof benchmarks/serialization.py $ flameprof out.prof > prof.svg...

If you ever have a little free time— I'd like to use the SVG-generating code not for `pstats`, but for my own datastructures (see https://github.com/itamarst/eliot/issues/220). My original thought was to...

Reliable benchmark results (even in noisy cloud VMs) with Cachegrind

Hi, One issue with running benchmarks is the need for a consistent hardware environment, which reduces the ability for people use things like ASV. I've spent a bunch of time...

Probably want to e.g. check if `/var/run/docker.sock` is readable/writeable and then prefix sudo if it isn't: https://github.com/datawire/telepresence/blob/38b808dff4ed45fdb0635eaa2418d3020169da1a/cli/telepresence#L152
