Is this an actual problem in practice? Have we had issues with the JSC internal killer not working?

It looks like yes, see <rdar://problem/61353156>
Though I am not sure why it is not working

Should be 'has timed out, killing with the timeout monitor'

I don't think the comment here is particularly helpful.

I feel like we need to replace this with Python in the near future....this feels incredibly hackey.

agreed, the script writer may need to generate the pure python code, however I am not sure if that can be run on playstation port, maybe firstly we just change the default one

I will change this to just kill jsc process instead kill the whole runner script, this should link the reset error handler instead of repeat it in the timeout monitor process

I'm surprised the style-checker is happy with this.

'Seconds' and 'Let jsc timeout...' should have their first leter capitalized

Should be "has timed out"

This seems to break all JSC queues. I'm explicitly disabling that for Linux, since current timeout monitor script doesn't work there (https://bugs.webkit.org/show_bug.cgi?id=213017).
