[BUG] memory leak

[nnym]

Describe the bug

Btop leaks RAM continuously while running: on startup RSS is ~23M and over ~60 days with update interval 1000 ms it leaked over 500M. Around that point it became very slow and crashed after a few key presses.

Most increments are of 160 B.

To Reproduce

1. Run btop.
2. Wait a while.

Expected behavior

Since btop retains a fixed amount of statistics, its RSS should remain close to its initial value.
