Super quick webpack compilations and writes leads to cache usage

[mzgoddard]

This may actually be a bug in webpack. When using webpack in watch-mode or in the dev-server (which uses watch-mode) if a file is written to, webpack compiles, and written to again, the second webpack compilation will include the the version from the first compilation of that file. Best signs from hard-source shows that modules are correctly invalidated. But it may be some other bit from hard-source causing the module to still use the old info.

This is highly unlikely to affect users though considering the the circumstances required.
