Option to restart incremental compiler

hi,

how feasible would it be to have - at least for the 2.8 nightly - an
option to restart the incremental compiler in the eclipse plug-in? i
realize it crashes very quickly after launching eclipse, and then the
incremental build is off, meaning that you need to call clean all the
time (which takes a lot of time)... maybe all it needs is a menu-item
that lets you explicitly restart the incremental compiler so you
don't need to exit and relaunch eclipse?

another thing i have ATM is lots of errors of the form

scala.tools.nsc.FatalError: Companions 'class XYZ' and 'object XYZ'
must be defined in same file.

where XYZ is basically any kind of class i have, both case classes
and regular classes (even if they don't have any companion object!)

thanks, -sciss-
