Panic recovery of a database - eg, BatMOO


Hi.

It appears as if BatMOO was saved by another method, but here is 
something I've knocked up that should work to the extent of re-creating 
your entire DB, to perfection, with the sole exclusion of forked and 
suspended tasks.

I have tested it on my system, connected via 'Local Loopback', ie, both 
the MOO and I are running on the same machine, and not actually over the net.

I have no idea what the result of trying this over the net will be.  Lag 
might cause serious problems with the high frequency of notify() calls, 
resulting in buffer overruns, etc.  If that is the case, sprinkle a few 
liberal suspends(10) or so in the code.  I just don't have the time or 
inclination right now to do a full net test.

I'd appreciate an independant test and some feedback.

	Ian.
