I've already said it, but I re-iterate - 32 bits is fine with me. 64 bits
is fine with me.

signedness makes wrapping harder. I see absolutely no reason for it to be
signed. Unless someone can show me why it needs to be signed.
I also advocate not using timestamps as offsets. Rather as absolute
timestamps, where each process() call gets a 'now' value of the timestamp at
the start of the buffer.
