Yep, that's the most likely reason.  We should probably reserve some
bytes for extra arguments passed by the compiler.  I can't think of
any good rule, though...  Maybe set usable_cmd_len to
max(max_cmd_len-1024,max_cmd_len/2)?

Ok.  One more thing to keep in mind: it would probably be good to get
max_cmd_len cached eventually.

Ok, but without the line-break, since the modifications are part of a
single change.
