An idea I had for a similar problem is kthreadd. This would be a kernel thread created on boot (just after kswapd), which would sit around waiting for requests to spawn new kernel threads. These thread's would therefore have no user VM.
I haven't decided upon the actual mechanism for talking to kthreadd, almost anything would do - e.g an internally opened pipe, down which three values (long & pointers) are shoved, or some other trick.
