The opcode space is laid out as follows:

• Normal instructions
• Gap (>30 instructions)
• RESUME (opcode 149)
• Specialized instructions
• Gap (3 instructions)
• Instrumented instruments

If we need to add four more specializations and/or instrumented instructions we will run out of space.
The fix is obvious: Renumber RESUME to something like 128.
