 What "recidivim -u M" prints is the memory use for one input. You
 shouldn't use this number directly for afl-fuzz memory limit, because
 other inputs will almost certainly require more memory. I'd add at least
 50 to this number (possibly more, depending on what the target program
 does).

 So maybe add a hint to the README?
