about QTro packet (tracepoints)

[ankit thukral]

 hi all,
        i was reading the packets' format in GDB for
 tracepoints (like QTStart,QTinit etc.) and came
 across
 "QTro" packet format.i learned that this packet
 transmits the addresses of all the LOADABLE
 READ-ONLY
 sections to the remote stub so that the latter can
 always entertain a request for data belonging to
 these
 address ranges,even if this was not specified as a
 tracepoint action by the user.
       would it not be a better option to let the
 remote stub collect this information of it's own
 (from
 it's own copy of the executable) rather than GDB
 transmitting it across the network which definitely
 is
 more costly in terms of time delay suffered by the
 process which becomes all the more costly while
 debugging a real-time application?
 
 hoping for a discussion on this,
 ankit.
