Android: Temporarily disable orientation changes in an Activity

My main activity has some code that makes some database changes that should not be interrupted. I'm doing the heavy lifting in another thread, and using a progress dialog which I set as non-cancellable. However, I noticed that if I rotate my phone it restarts the activity which is REALLY bad for the process that was running, and I get a Force Close.

What I want to do is programatically disable screen orientation changes until my process completes, at which time orientation changes are enabled.

In order to manage also the reverse orientation modes, I have used that code to fix the activity orientation:

int rotation = getWindowManager().getDefaultDisplay().getRotation();

    switch(rotation) {
    case Surface.ROTATION_180:
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT);
        break;
    case Surface.ROTATION_270:
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE);         
        break;
    case  Surface.ROTATION_0:
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        break;
    case Surface.ROTATION_90:
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
        break;
    }

And to allow again the orientation:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);
