I thought I mentioned it here already, but seems like I didn't. Inspired by
Brunos idea I've added a similar proof-of-concept patch to Wine Staging, which
addresses exactly these problems:

Using exec in Wine in general is not necessarily bad, but it would of course be
better to have only one "ping service" running instead of one application for
each request. Besides that the idea seems to work very well and is indeed
sufficient for a lot of applications, especially because additional
input/output parameters are translated.
