Just leave your IW open forever and periodically reopen your NRT reader. Be sure you close your old NRT reader after opening a new one; SearcherManager makes this easy when multiple threads are using the readers.
Committing every 200 docs seems quite frequent: commit is very costly, and it's only needed for recovery (so you know which docs are in the index if the machine/OS crashes).
