This time I got an error during check-all, on i386-unknown-freebsd10:

This is because the ulimit -t 600 was exceeded, as shown in dmesg:

    pid 78288 (python2.7), uid 1000, was killed: exceeded maximum CPU limit

Can we bump the -t limit a little?  If a machine is rather busy when doing the tests, this limit can be exceeded.  I had this diff for trunk for some time:
