.generate_guid(length = 16) ⇒ Object

This method intentionally does not use SecureRandom, because it relies on urandom, which raises an exception in MRI when the interpreter runs out of allocated file descriptors. The guids generated by this method may not be secure, but they are random enough for our purposes.
