pyrasite can make the child process slow down markedly; this came up for me when injecting profilers into cinnamon-screensaver to try to root cause a memory leak (https://bugs.launchpad.net/linuxmint/+bug/1652489)

cinnamon-screensaver would take multiple seconds to lock the screen even after I'd stopped profiling and exited the interpreter I'd injected, and I wound up restarting it so I could lock my screen quickly again.

I don't know why this happened, but it's enough to make me think twice, and I'm definitely going to double-check my process is still performing as I hope after injecting it with pyrasite in the future.
