+
+		- whenever you *don't* send a stackblock, send the cookie
+		  instead. That way you always get a complete stacktrace

+		- also, that would allow the kernel to just have a simple
+		  hashtable containing the known blocks. Though, that could
+		  become large. Actually there is no reason to store the
+		  blocks; you can just send the hashcode. That way you 
+		  would only need to store a list of hashcodes that we

 * If interrupt happens in kernel mode, send both
   kernel stack and user space stack, have userspace stitch them
   together. well, they could be stitched together in the kernel.
