Best way to ulimit subprocesses?

[timkpaine]

What is the best way to ulimit subprocesses right now? Something along the lines of #218 that can be injected prior to kernel launch.

[timkpaine]

My current strategy is to use custom jupyter kernels that impose resource limits/niceness on startup

[jtpio]

By custom kernels do you mean wrappers around existing kernels?

[timkpaine]

sort of, we have custom wrappers around ipykernel anyway, i just injected a bit of code to set rlimits before deferring to ipykernel's launch

[timkpaine]

(this is not portable to other installations though, so ideally voila can handle this itself)

[jtpio]

Using resource.setrlimit() from the standard library?

[timkpaine]

Yep

[timkpaine]

closing, using custom kernels
