 /*
  * [What's the purpose of this hook?]
- * Calling unshare twice invalidates existing FD links, which fails Zygote sanity checks.
- * So we prevent further namespaces by hooking unshare.
+ * Hooking unshare is necessary to stop Zygote from calling unshare a second time,
+ * because that breaks the FDs. We handle this by reopening FDs,
+ * allowing us to call unshare twice safely in our callback.
  *
  * [Doesn't Android already call unshare?]
- * Whether there's going to be an unshare or not changes with each major Android version
- * so we unconditionally unshare in preAppSpecialize.
- * > Android 5: Conditionally unshares
- * > Android 6: Always unshares
- * > Android 7-11: Conditionally unshares
- * > Android 12-14: Always unshares
+ * Android's use of unshare changes with each major version, so we always call unshare
+ * in preAppSpecialize.
