serial transmit response latency

As I explained in another post, my cd changer implementation requires that I
respond to polling requests within 8ms
I took the software Tx patch posted by jorg, and noticed that the software
Tx implementation is a software loop polling the timer.
Can I use such transmit routines inside the serial interrupt?
Is there a problem having the serial interrupt taking 3-4 ms?
Are there other time critical tasks in rockbox?
If the transmit routine must be done outside the interrupt, where can I be
assured to poll every millisecond?
Final question: will the software tx patch be merged into cvs?
Thanks a lot for your help.
