Bugfixes

Reverting behavior for unblockSelectorSignal SDK flag

The previous fix introduced with the SDK flag unblockSelectorSignal was found to have a different bug with losing signals. For now the flag is getting turned off, and a more robust solution will be re-introduced in a future release. If anyone happens to rely on this new behavior already, the UNBLOCK_SIGNAL_SELECTOR env var can be set to enable the SDK flag.
