Subject: [PATCH] IPC: handle EMFILE as an OutOfResources error
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In QSystemSemaphore (QSharedMemory already has it).

When running tst_QSharedMemory::useTooMuchMemory on 64-bit Linux with
POSIX IPC, we run out of file descriptors before we run out of memory.
