Techniques are described for utilizing synchronous APIs which normally block callers until a result is returned. In particular, the techniques described herein enable an application or other programming construct to boost performance by executing synchronous APIs (e.g., long running time APIs) within a proxy container rather than executing the synchronous APIs in the context of the application itself. Since the proxy is a separate process or thread, the caller application is thereby released from waiting for the synchronous API call and may proceed with other processing instead of waiting for the synchronous API to return. The application may then monitor the proxy to determine whether a result has been received, such as by periodically polling the proxy.

Communication facilitated between frames of a browser window. Whenever a particular frame receives a message destined for a target frame from a source frame, the particular frame determines if the particular is indeed the target frame. If so, the particular frame processes the message, but if not, the particular frame determines whether the target frame has registered with the particular frame. If the target frame has registered with the particular frame, the particular frame uses a handle communicated as part of the registration to dispatch the message further towards the target frame. In some cases, this handle may be directly that of the target frame itself, in which case the particular frame communicates the message directly with the target frame. This manner of inter-frame communication may be facilitated by a unique registration process when frames come into existence.

Specifically, in a typical embodiment, when a computerized process is identified, a physical page key (PPK) is generated (e.g., a unique PPK may be generated for each page of data) and stored in at least one table. Based on the PPK a virtual page key (VPK) is generated and stored in at least one register. When the process is later implemented, and a request to access a set of data associated the process is received, it will be determined whether the VPK is valid (based on the PPK).

The callback is queued for execution in the requesting thread and so has a deterministic execution context. Callback queuing may occur in response to another thread detecting that the request is complete.
