pystack exhausted 6.0.0-alpha.2 on PyPortal

[anecdata]

This is a placeholder issue. I don't have a minimal reproducible example, but alpha-2 breaks my main IoT application with pystack exhausted. 6.0.0-1 and prior are fine. The code makes it through all of the setup, including displayio and esp32spi, but it seems the HTTP GET triggers the error. The library refactoring underway may well help.

I believe the latest version off main will work ok. Mind trying that? We just need to release it.

pystack appears to have gotten enough rest by CircuitPython 6.0.0-alpha.2-296-g6e5c2b3fe on 2020-08-17 (latest S3) :-) Thanks! (Github search for "pystack" yields no code or commits)

Glad it worked!

I turned on pystack here: #3160 and the size was bumped here: #3213
