Wow, this patch made a big improvement!  On the nios2 board the startup 
took 18 seconds the first time and 10 seconds on subsequent attempts -- 
probably some NFS-level caching?  On the PandaBoard it was 3 seconds or 
less.

Unfortunately, I still can't see that ^C is doing anything useful for 
me.  It is not coming back to a gdb prompt any sooner and "info 
sharedlibrary" afterwards prints the same thing whether or not I've 
tried to interrupt it.  This was with unpatched FSF trunk.  How am I 
supposed to tell whether ^C did anything?  How are you guys telling that 
it is doing something useful?  Is there supposed to be some sort of 
message?  If the file transfer from the target is aborted, I think it 
should say that.

I'm also not seeing the warning on the initial sysroot file transfer 
from the target.  I've lost track of this; was that patch not 
approved/committed yet?
