rojo doesn't terminate on interrupts like Ctrl-C

[mstarostik]

Rojo 7.2.1 installed via foreman on Linux.

When hitting Ctrl-C (also tried Ctrl-\ FWIW), the rojo serve foreground process is terminated as expected. ~/.foreman/tools/rojo-rbx__rojo-7.2.1 serve however keeps running and prevents another launch on the same port.
Killing that one frees up the port of course.

Rojo should fully terminate on Ctrl-C instead.

Hello, thanks for filing an issue!

This is not a Rojo issue, this is a Foreman bug. See Roblox/foreman#45.

You might consider switching to Aftman, which does not have this bug.
