Dtrace buffer panic survival and a way to recover whatever is left from ddb/core dumps for post-mortem analysis

E.g. memory modified after free debugging, other changes leading to a panic in drivers. There is no way to actually track the last <n> > frees anymore to figure out where the memory was freed (and hence possibly used after); Dtrace would be a fantastic tool to just do that… if we'd get everything up-to until the panic out of the buffer. Obviously the other bit is to ensure the file streamed to is recoverable. Not sure what happened to a “network dtrace”.
