You can assuming you start with a pointer (or an iterator) to the
relevant node, and have somewhere to toss the garbage.

Intrusive linked lists are particularly nice for realtime they avoid the
need to allocate to insert into the list.  Thread-safe insert (prepend)
is easy as well, if it's singly linked.
