[AUCTeX] Clear up output buffers

[Shug Boabby]

hello everyone,

AucTeX creates a lot of temporary and output buffers when it compiles  
a file... is there a variable to automatically close _region_.tex and  
output buffers after successful compilation? failing that, doing it  
in a post-compile hook would be the perfect place to do this  
in .emacs... are there any such hooks?

i am currently experimenting with a mode for marking buffers as  
temporary and then it auto removes them when they are seen to be unused:
  http://www.emacswiki.org/cgi-bin/wiki?TempbufMode
but i am having trouble using it with AucTeX. all the output buffers  
seem to have the major mode LaTeX set. and if i run tempbuf for all  
LaTeX modes... that could get messy.

what are the hooks available to me regarding the output and temporary  
buffers?

it'd also be nice of AucTeX to close the master buffer if it opened  
it during a C-c C-b call.
