Note that all file data in this class gets serialized to and from memory, as such, the design intention for this class is for use with smaller data sets such as serialized lists or dictionaries that need inter-process synchronized loading and saving.

The InterprocessCache uses a NamedSemaphore to synchronize access to cache as an inter-process shared resource. On POSIX systems, the NamedSemaphore exhibits kernel persistence, meaning instances will remain active beyond the lifespan of the creating process. The named semaphore must be explicitly removed by invoking ReleaseInterprocessResources when the last interprocess cache instance is no longer needed. Kernel persistence necessitates careful design consideration regarding process responsibility for invoking the ReleaseInterprocessResources method. Since the common use case for named semaphores is across multiple applications, it is advisable for the last exiting process to handle the cleanup. In cases where an application may crash before calling the ReleaseInterprocessResources method, the semaphore persists in the system, potentially leading to resource leakage. Implementations should include strategies to address and mitigate this risk.
