As Ben said, older testsuites could hang. This usually happens if some test
process crashes and others waits for it. Default timeouts was introduced for
tests in more recent branches. There are also some bad race conditions that
could lead to waiting of finished processes.
However, testsuite on branch-2.6 runs fine for me. I don't know what your
exact issue is.

Fix for above two branches is on a list:
    https://patchwork.ozlabs.org/patch/1048316/

But it's not merged yet.

2.11 builds/tests fine on TravisCI. There should be no issues.
On which system you're trying to build?
