Is allocating a scratch buffer in gdb really such a big issue?
It's very late for proposing libunwind API changes.

Draging that entire buffer (128k in the case of a program like GDB) across the remote link is going to raise a few eyebrows so a careful examination is justified. If that search is so critical can the algorithm be made more efficient? If it isn't then, per my suggestion, have the code use the memory method as a fallback.
