It basically reads memory from the target in a buffer in gdb_disassembly and tries to use this buffer in dis_asm_read_memory instead of reading from the target. This saves us on repeated memory read calls. The problem was noted when eclipse was trying to fill its disassembly view.

This is a specific fix to a general problem.
Question: How much more of the general problem can we fix without
having a fix baked into the disassembler?
