> Felix Meschberger wrote on the Sling dev mailing list:
> The ScriptHelper.getService(Class) method of the Scripting Core bundle
> implementing the SlingScriptHelper API allows scripts to get access to
> OSGi services. This all works perfectly in that the method just forwards
> the call through to the framework.
> At the end of running the script, the service is then "unget".
> Now, the framework will guard access to the service registry and if a
> lot of requests are asking for a service while processing the request,
> even calling repeatedly for the same service during request processing,
> this may result in a contention on the service registry.
> I wonder if we could do better with this method by caching the services
> not only for the time of processing a component but for longer time,
> either during complete request processing or even in a size constrained
> cache (of course unregistered services will have to be removed).
