Ah hah. This did subsequently get reported by someone else

I bet.

Is /tmp noexec by default on current redhat/centos releases? If so we'll
want to up the priority of these tickets.

If /tmp is noexec, do you know what is the recommend solution on these
platforms. For compiling packages we need to be able to compile and
execute programs. Is there some other location other than /tmp that we
should use?

I wonder if there's a quick and reliable method for testing for noexec,
rather than waiting until we get to the stage where we've unpacked the
package, compiled Setup and are trying to run it.
