Needless to say that what you do is totally unsupported and will
totally break in 10.6.
10.6 now provides a public (incompatible with Leopard) API but even
with this API, what you do is greatly unsupported (and will break in
the future). Add to that the fact QL panel is very asynchronous, and
it's expected for you to encounter a *lot* of problems.
