So my questions are: is this aliasing a particular problem of my system or is this an expected result?
It's an expected result. It isn't 'aliasing', but an effect called quantisation, which you will hear even in perfectly sampled data.
Is there anyway of avoiding it? I could post the patch here if needed.
[tabread4~] already goes some way towards avoiding it, by interpolating (going in-between the sample values) to make the playback smoother. Since you seem interested in the low frequencies found when slowing sounds down it might help to add a low pass filter that smoothes the signal even more.
