But further to my case, I've checked the periodicity of the thread and it does 
seem that with 5 ms I get to handle pretty
much exactly 220 frames per iteration (which is pretty stable), but still I get 
the pops/clicks.

I've found the problem. With profound stupidity I assumed that the position 
register would be aligned to the block alignment size (4 bytes in the
case of 16 bit stereo). This was not the case, and I guess this would be pretty 
common. After aligning the position the pops/clicks are gone :)
