Rather than the MIPS, check the x86 family for how to add a custom sigtramp handler (ex, i386_sigtramp_frame_sniffer). Hopefully the new mechanism is less baffling - the current MIPS code is not a good reference.


But since he's got a MIPS target, the frame sniffers won't help him at
all, will they?  They can't be used until the MIPS is converted.

Looks like Kevin may have drawn the short straw.
