[mohaa] MOHAA linux server with potential exploit fix.

[Ryan C. Gordon]

Spoke with Luigi, and it's only a partial fix; new build should be more 
robust (and have a legitimate UBoat-spawn fix, too).

Here it is:

Same deal as last time, don't consider this to be production quality 
yet, and I haven't tested it at all because I'm still sitting in a hotel 
room in another country.  :)
