Timeout on eval-system too agressive?

Describe Bug

eval-system sometimes fails to capture output of a command.

I suspect this is due to a too short timeout in lolly::system::check_stdout .

I have tested this with (eval-system "python3 /home/jeroen/test.py"), where test.py contains

import time
time.sleep(0.2)
print("hello world")

Depending on the delay the output is captured or not.

Expected Behavior

Output is captured.

I verified the issue in lolly. It can be resolved by increasing the timeout in subprocess.hpp from 20 to, say, 2000. However, the longer the timeout, the longer subprocesses take to return.
