> It looks like it does skip calling ftruncate() if size is 0. From posixshmem.c:

Let me rephrase: are we forced to specify a value (aka call ftruncate()) on create ? If we are as I think, could size have a reasonable default value instead of 0? Basically I'm wondering if we can relieve the common user from thinking about what size to use, mostly because it's sort of a low level detail. Could it perhaps default to mmap.PAGESIZE?
