Continuing reports of deadlock between threads accessing and loading the C project descriptors. This and the rest of the build system needs a revisit.
Scalability issues with CDT indexer have been investigated. Some have been fixed but projects like Boost run out of memory at index time. Investigation will continue towards 8.5.
Largest change is spliting out CDT's native services, the Spawner, PTY handler, and Win32 registry access, has been split into a new feature and bundle. The CDT core fragments are now fragments of this new bundle, org.eclipse.cdt.core.native. Changes have been made to ensure the API is re-exported from their old home in cdt.core. This was done to support the TCF terminal view without dependencies on the entire CDT platform. This is a candidate for moving to a Commons project to be shared with other projects.
