Fix: don't SIGBUS when filesystem is full

Write zeroes into the buffer after its allocation to ensure that writes
to the shm will not trigger SIGBUS upon full filesystem situations.

This scenario can occur if /dev/shm is filled, e.g. by specifying too
large buffers with --enable-channel.

When the write() fails, the buffer creation for this channel fails.

Fixes #230
