I have an Arduino-like device (a Particle Electron) that is continually spitting out strings via USB.
When I monitor it using particle monitor serial it behaves as expected.

When I monitor it using Alpha 5 p5.serialcontrol (and a simple p5 sketch to display the strings), it initially runs fast, but soon starts slowing down and eventually stopping.

Watching its memory usage, p5.serialcontrol starts at 150 MB, but before long has bloated up to > 1GB and eventually crashes.

I suspect a memory leak. LMK if a code example would help.
