cowasm.sh: sometimes running python more than once leads to "Fatal Python error: init_sys_streams: can't initialize sys standard streams" #42

Open williamstein opened 1 year ago

williamstein commented 1 year ago

This is presumably just some state involving /sys/stdout, /sys/stdin, etc. with our "run a subprocess" functionality.

It happened in this session using https://cowasm.sh

Type 'ls /usr/bin' for a list of commands, including python (with numpy), lua, sqlite3, date, and du.
This is new and *many* things are not implemented.  Output redirection and capture is not implemented.

This is caused by outputing a bunch of random binary "crap" to the terminal. From a fresh shell:
