I understand that if there are no matches in my receive block, a message is placed in a save queue until a valid message match appears in the future. How large is the save queue? If I spam my victim process with messages, will the messages eventually fall off the end, or will they just stack up until I am out of memory, or is there an option C here?

The mailbox size will continue to grow until the VM runs out of memory. This problem is solved in OTP behaviours, where through a callback mechanism, you have to handle the messages in the order in which they arrive, removing selective receives.
