I'm afraid this is an intermittent problem that's more likely to 
occur under heavy load. For example, on an RHEL 7 system:

bash-4.2$ for i in `seq 1 100` ; do

iolint
./iolint.ok _iolint differ: byte 341, line 11
make: [iolint] Error 1 (ignored)

So I believe there's still a race condition here.

The problem occurs more often when I run "make -j check".
