Hello folks,

it seems the RPC service can be run as normal process using '-no-service'
command line switch for easier reproducing/debugging.

--- snip ---
$ winedbg ./EvoSvc.exe -no-service
--- snip ---

(start the client)

Unfortunately there is a watchdog timer which shuts the RPC server down after
30 secs.

Evolve is running...

2014-Apr-06 00:29:09.953202 - The client didn't connect within the expected
time. Shutting down service...
2014-Apr-06 00:29:09.955963 - Shutting down RPC server...

This one is responsible:

ret=00415470

0x7530 -> 30000 msecs

Patching the timeout constant at raw file offset: 0x14857

Power to the debuggers! :)
