    4343We plan to build a fully noblocking Objective-C API for Mac OS X as a wrapper on top of the C API. We believe a similar approach may be viable for other ports.
     44
     45We are also not removing or obsoleting any of the existing port-specific APIs. WebCore will remain as-is, and all current APIs will continue to work and be fully supported. Thus, WebKit development and existing ports of WebKit will not be disrupted.

     54There are two key subsystems that support the process division :
     55
     56* CoreIPC - an abstraction for general message passing, including event handling. The current implementations use mach messages on Mac OS X, and named pipes on Windows.
     57* DrawingArea - an abstraction for a cross-process drawing area. Multiple drawing strategies are possible, the simplest is just a shared memory bitmap.
