Disk usage keeps growing after an error?

[kr094]

Expected Behavior

Provide the directory where these are stored so I can clear them? Or do that automatically.

Actual Behavior

When hardsource hits any error it rebuilds a new cache. After having this happen a few dozen times it's started outputting a message about disk usage. The number is never going down so I presume this is never being cleared after a failure.

[hardsource:eb0ab0ab] Using 380 MB of disk space.

Is an error being thrown?

An internal es6 compilation error not within hardsource. To reproduce have any syntax error stop compilation.
