** Summary changed:

- pkgbinarymangler slows down all builds, unnecessory
+ pkgbinarymangler runs in parallel and is confusing

** Description changed:

- pkgbinarymangler slows down all builds, unnecessarily.
+ pkgbinarymangler installs dh_builddeb wrapper.
  
- pkgbinarymangler prevents running the io intensive dpkg-builddeb in
- parrallel which is the default.
+ instead of actually doing all the things and then executing the real
+ dh_builddeb, it instead only creates lockfiles, and then when
+ dh_builddeb spawns dpkg-deb some of them are starved awaiting lockfiles.
  
- instead of making the builds use dpkg-builddeb in parallel, it makes all
- packages getting processed serially for the symlink_doc functionality.
+ also the buildlog is very ugly, as it intermixes pkgbinarymangler output
+ with inflight parallel invocations of the real dh_builddeb/dpkg-deb.
  
- i wonder if we can integrate this better.
+ also it seems to not check return codes from dh_builddeb. as it calls
+ system{} without die, it should porbably instead do exec.
