Cleaning or rebuilding too much

Hello,

is there a known workaround for issue 
http://zigzag.lvk.cs.msu.su:7814/scarab/issues/id/BB37 - cleaning too much?

Summary: Running "bjam --clean" will remove all targets in dependency 
graph. It's quite confusing when
targets in other projects are removed, so we either need to change this 
behaviour, or give an option.

On a related note - how do you rebuild an executable that was once 
successfully built when you change some options in the Jamfile (adding 
some flags, defines...). Running 'bjam -a the_app' will rebuild 
*everything*, including ie all boost libraries and every library that's 
built using bjam. The only thing I was able to come up with was to go 
looking in the deep directory hierarchy created by bjam and remove the 
executable by hand :(.

Thanks for any insights.

Zbynek
