1st issue was that one of the ostream ops failed to print the
content of the struct.
2nd issue: get_ptr_type was called with args being src/dest
pointers while it should be the agents pointers for src/dest.
3rd issue: memcopies map used (recordid, procid, is_async)
as a key but this is not enough as some copies share same key,
so I added begin/end timestamps as a way to distinguish between them.
