Package: esix
Version: 1-3
Severity: normal

Dear Maintainer,
Expected results:
1. Launch esix in terminal
2. Interact with ESI-X language REPL
Actual results:
1. Launch esix in terminal
2. Interact with ESI-X language REPL
3. Computer CPU usage climbs to 100% as REPL busy-waits for input.
Suggested bug fix:
Modify /usr/share/esix/esix.cfg from:
load esix.bin
run 5400
to
set cpu idle
load esix.bin
run 5400
This will cause the simh PDP-8 emulator that runs the ESI-X binary to
throttle down when it detects a busy loop. It may take 25-30 seconds for
CPU usage to calm down.

but this issue is present in the upstream Debian esix.cfg file
