It didn't consider all forms of movem, just 0x48e7 which is the start of "moveml X,%sp@-". This matched page faults in many of the programs that executed while booting to single user mode. I suppose most of them don't use signal handlers in the same way dash does otherwise they would probably be unreliable too.
