Subject: fastbulk - More fixes and improvements
X-Git-Tag: v3.2.0~289

fastbulk - More fixes and improvements

* Fix improper cleaning of the "${BUILDROOT}/usr/obj/work" directory

* Use lockf to lock the wildcard name for a package, serializing the
  builds of any related packages so they don't interfere with each
  other.

* Clean the work directory on success or failure instead of only on
  success, othrewise a large >10G tmpfs is needed.
