Any module loaded in the child doesn't get reloaded for two reasons:
* devtools/server/child.js frame script doesn't get reloaded
  loadFrameScript caches scripts and unfortunately there is no way to force reload nor purge the cache. I opened bug 1258496 to address that.

* Loader.jsm doesn't get reloaded
  So that even if the frame script is reloaded the JSM keeps the same modules instances. We have to communicate with child processes to call its reload method.
I needed that in order to get chrome://devtools/locale/ to be updated.
That allowed me to work on menuitems and shortcuts via the addon.

chrome-flush-caches in child process is still at risk in bug 1258496.
May change this patch accordingly.
