Actually you used to be able to post in a locked thread but that ability was removed. This is because it could be exploited and people used a glitch in order to continue posting in a thread which was locked (as all that happened was the "reply" buttons and boxes were inaccessible). It is frustrating if you wrote a long post but my advice is at least for now copy the text on the (extremely rare) chance the thread is locked. Also I believe a simple click on the back arrow should return you to your post text intact.
