See commit 41b1792698 for testcase.
Note: while this works on s390x, the s390 code hangs when using -e.
But it hangs regardless of this code (the hang seems to occur before
the exit func is even called). I didn't look too closely at it as
it seems to be an issue external to this file, so this code shouldn't
make the situation any worse.
