[pkg-php-pear] Bug#1120583: symfony autopkgtest sometimes uses insane amount of memory on ppc64el

Dear maintainer(s),

I just had to kill an autopkgtest run of your package because the system 
was about to run out of memory on our ci.d.n infrastructure. After the 
kill there was 220GiB extra free memory available. Not all runs seem to 
using that amount, and most runs seem to also finish much quicker, so I 
suspect a race condition where both execution time takes longer and 
memory consumption goes haywire. The test also seems to be rather flaky 
on, not only on ppc64el.

Now there's an argument to make that the infra should protect itself 
against this kind of misbehavior, but currently it doesn't (we're 
working on that). I would appreciate it if you can find a way to ensure 
the test behaves.

Paul
