Gnulib module: explicit_bzero
explicit_bzero function is an approximation to what is
needed, and does not suffice in general to erase information.
explicit_bzero should clear the memory in
question, the information that was in memory may still be available
elsewhere on the machine. Proper implementation of information
erasure requires support from levels below C code.
