Yes, it is. And T-bit is when the T-bit in the PSW is set. That is how 
debuggers single step code. So T-bit and BPT are very much just two 
sides of the same coin.

Ok. Memory shortage is the one thing I can imagine could cause something 
like this. If a program runs out of memory, the programmer could just 
have thrown a BPT in there as a way of crashing out.

Otherwise I'm not coming up with any good ideas here...
