'make check' hangs because ./check_pool_local_multi hangs and seems to be leaking memory

I have tried on two different linux systems and in both cases ./check_pool_local_multi seem to hang after calling the linux initialiser:

[D] (6178): mmb_init(mamba.c:114) Mamba library initialised, version: mamba 0.1.1 [D] (6178): mmb_init__linux(interfaces/linux_native.c:59) Calling linux initializer()

It looks like a memory leak because top reports continuously increasing memory. The process eventually OOM-killed after running out of the available 32G memory.
