Oeps, Didn't change the title of this bug. Lets say :
"Engine crashes after a few games..."

Yeah I know, the Oracle is bugged.
At this time, it plays a game, with depth 1, and then does a lot of undos, when 
a
player moves, after which it starts playing.

When the new engine system is finish, the oracle will probably be using the 
"analyze"
command of the xboard protocol, which should changes thing dramatically.

Perhaps I should commit my changes. I've been holding a bit back, as they'll 
break a
lot of features, but on the other hand, the svn is "nightly release", right..

impact
will be big....

I close this bug, as revision 51 has changed a lot of stuff.
