Generally speaking, we’ve had a long tail of issues that only show up during teardown that we’re avoiding. Leaking resources that will be reclaimed by the OS when the process terminates is a non-issue. If there are specific scenarios where a long-lived process leaks significant content that isn’t an effective cache for subsequent use, please outline how that manifests.<div class=""><br class=""><div class="">
