There's also this, which I still haven't checked in: http://sourceware.org/ml/gdb-patches/2011-03/msg00606.html This defers reading debuginfo for new inferiors until some event happens that requires it. It turns out that Gary's recent patches will (most likely -- I didn't try it yet) fix the problem pointed out in that message. Anyway, this approach does help quite a bit. Tom
