You're also doing a linear search, which can be costly if you have a huge number of open streams, a hash table may be much faster. If you have a small number it may be overkill.

It may also be that most of your work is already I/O bound, hence little gain is to be had from optimizing the code. Given the ludicrous speed of modern computers relative to modern disks I suspect this is the case.
