        assertTrue(file.exists(), "File should exist after creation");

        // Ensure proper cleanup before delete
        file.close();
        Thread.sleep(500); // Give more time for handle release
        System.gc(); // Force garbage collection

        // Delete using a completely new context to avoid handle issues
        CIFSContext deleteContext = createFreshContext();

the number of items in the channel corresponds to the number of active uses,
the capacity of the channel corresponds to the maximum number of simultaneous uses,
sending an item acquires the semaphore, and receiving an item releases
the semaphore.
This is a common idiom for limiting concurrency.
