(char, Bigarray.int8_unsigned_elt, Bigarray.c_layout) Bigarray.Array1.t
We consider 1-dimensional bigarrays of chars as memory buffers.
They have the useful property that the garbage collector cannot
relocate them, i.e. the address is fixed. Also, one can mmap
a file, and connect the bigarray with shared memory.
