[Converted from Gnats 1522]

 Hello,
 
 At present the selected and current frame are maintained as single 
 globals, and independant of the selected and current thread.  As a 
 consequence, each time GDB switches between threads, all global frame 
 state is flushed.
 
 I'm intending to add a "current frame" and "selected frame" to 
 "thread_info" so that, instead this can be maintained on a per-thread basis.
 
 The tricky one is the sentinel-frame.  It needs to be able to perform an 
 arbitrary projection of the virtual thread's register onto the target 
 below's physical threads and memory.   I think this suggests a 
 sentinel-frame parameterized by target, and not just the current regcache.
 
 Thoughts?
 Andrew
