We're both going to learn from this experience, then (I did the MacOS 
version, which is definately very different from the Linux version).  I 
suspect that there will be a way to reduce the problem dramatically, and that 
it will be a matter of reducing the amount of AL activity associated with 
high-intensity moments.  Playing additional sources will of course impact the 
performance, but it shouldn't be that bad.  I think that it will be a matter 
of reducing other activities -- looking for a free source, playing many 
sources with the same effect rather than looping a single one, ...
