Sorry, you're right -- I'd mostly be interested in the linkmap, and 
forgot about the other request types. I'm hoping the former would help 
introspect unwind sections to construct accurate backtraces from within 
an app. No big deal, tho. I'll play on a linux machine until I see 
whether it's compelling enough to be worth porting to cygwin.
