bokeh serve error with directory format and --num-proc != 1

I am using the directory format with a bokeh server that has a structure like:

   fst_app
>
+---main.py

snd_app

±–main.py


If I set --num-procs to any integer other than 1, then I get the error message:

ERROR:'DirectoryHandler' object has no attribute 'safe_to_fork'

``

The command is:

bokeh serve --num-procs 0 first_app snd_app

``

The error occurs even with only one app specified, but I can explicitly pass --num-procs 1 without issue. I can also run the [single module format](http://bokeh.pydata.org/en/latest/docs/user_guide/server.html#single-module-format) with any number of processes. Is this a bug or am I using bokeh serve incorrectly?

Great, assuming it's as simple as I imagine, I should have a fix in master today.

Thanks,
