The collection process, created using clone, is similar to a normal `fork()` child process, except that it shares the address space of the parent - any writes by the original process are visible to the collection process, and vice-versa. If we forked instead of using clone, the address space might get out of sync with observed post-ptrace thread state, since it takes some time to pause the parent.
