Now that we have timestamps on FORK, EXIT, COMM, MMAP events we can sort everything in time order. This fixes the following observed problem: mmap(file1) -> pagefault() -> munmap(file1) mmap(file2) -> pagefault() -> munmap(file2) Resulted in decoding both pagefaults in file2 because the file1 map was already replaced by the file2 map when the map address was identical. With all events sorted we decode both pagefaults correctly.
