Hey! I see that this is your first PR. That is great! Welcome! Symfony has acontribution guide which I suggest you to read. In short:
Review the GitHub status checks of your pull request and try to solve the reported issues. If some tests are failing, try to see if they are failing because of this change. When two Symfony core team members approve this change, it will be merged and you will become an official Symfony contributor! I am going to sit back now and wait for the reviews. Cheers! Carsonbot |

the ErrorException originates from a php warning
instead, I suggest using this (and removing the new method):
$resource = @sem_get($keyId);$acquired =$resource && @sem_acquire($resource, !$blocking);

I was not sure if @ operator can suspend exceptions, this looks nice. I go change this.
