Hello L4 Hackers,

a long time ago (*), Jochen Liedtke described a potential denial-of-service 
attack against the L4 kernel by -IIRC- requesting a huge number of mappings, 
thereby exhausting kernel memory. Does this issue still exist in the current 
L4 implementations or has it been solved (How?).

Kind Regards
