os/exec: TestExtraFiles fails

[gpaul]

go version devel +d8c952ef0940 Thu Mar 13 18:26:01 2014 +1100 linux/amd64

What steps reproduce the problem?

I saw this while looping run.bash --no-rebuild with random GOMAXPROCS

...
=== RUN TestExtraFiles-8

Comment 1:

The following reproduces the issue after a couple of loops.
for i in `seq 1 5000` ; do  export GOMAXPROCS=$[ 1 + $[ RANDOM % 128 ] ]; echo
GOMAXPROCS=$GOMAXPROCS; go test -v -short os/exec; done 2>&1 | tee exec.log
