No, it really isn't that slow.
SyncModular does a similar trick.
it'd still be interesting to know how the sync problems this
method poses are solved: you cannot rely on executable code
modifications to be atomic. an indirect jump instruction is
not guaranteed to work ok: a pointer on x86 is 32 bits, and
atomic is 24 bits (besides, indirect jumps have ill influence
on the cache). could do this with branching though -- but you
don't want your dsp code interspersed with volatile if()s.

Not if it
generates machine code. That way, it could (theoretically)
in realtime? we'll need everybodies' spare cpu cycles!
