Loading a bundle into a running program (gdb->Hacks)

Sometimes it's handy to load a bundle into a running app to do some poseAsClass: for doing some debugging or reverse engineering. Make a Cocoa bundle which has the code you want to load, then do:

(gdb) call (id) objc_getClass("NSBundle")
$1 = (struct objc_object *) 0xa0a051d8

gdb) call (id)[$1 bundleWithPath:@"/blah/blah/PoseAsClassBundle.bundle"]
$2 = (struct objc_object *) 0x51467e0

(gdb) call (BOOL)[$2 load]
