Hello,

bpytop is an awesome monitoring app, thanks for making it. However i frequently get these crashes across all FreeBSD versions, kind of a bummer.

To Reproduce

Start compiling chromium (or any ginormous chunk of code) in one term, run bpytop in another, watch is crash a few time.

[Steps to reproduce the behavior:]

Explained above.
