why isn't this a DynamicServiceRunner?

[Nick Bray (chromium), 2015/01/29 22:31:35]

Because DynamicServiceRunner has assumptions about shared libraries baked in:

https://github.com/domokit/mojo/blob/671001e79618e4e1445524af66356144444984fd...

I could either ignore this method (meh), or factor out a "DynlibServiceRunner"
class that contains it.  Semi-unrelated, but I had been thinking about trying to
move all the files that assume dynamic libraries into //shell/dynlib or
something like that.  Splitting the base class could be part of that move.

Done.
