Make subprocesses nice #58

Open sburnett opened 10 years ago

sburnett commented 10 years ago

Use the nice syscall to decrease priority of sandboxed execution.

This doesn't work as well as you might think. Nice is remarkably ineffective. (I'll share a paper with you that talks more about this.)

We did polling and then use SIGSTOP / SIGCONT (at least of Linux systems) to better enforce CPU restrictions.
