Crazy things you didn't know about OpenSSI

Did you know that the kernel migrates processes by writing to 
/proc/pid/goto?!#

(I.E. proc_migrate calls do_ssi_write, and not the other way round!)

(This may be a problem 'cos do_ssi_write has a silly 256 byte buffer on 
the stack to read the stuff written from user space).

(Also it's crazy - to migrate a process the kernel has to snprintf the 
nodenum, so do_ssi_write can sscanf it!)
