If it works like system(3), the return code looks like this:

BITS  MEANING
0-6   signal which killed your child process
7     did child process core dump?
8-15  exit status of child process

126 still seems odd, though.  It means you got a 0 return code, it
didn't dump code, and the child aborted with signal 126.  However,
126 isn't one of the standard signals.

Strange...
