Description:
------------
sysvmsg extension

I tested on arm raspbian buster 10, 32 bit (php 7.3.19) and ubuntu 20.04, 64 bit (php 7.4.9), both are same.

I have long running process, which is executed by supervisor, where is passive waiting for message from queue, but this waiting is sometimes awakened by error code 43.

I checked that the supervisor runs only one php process and the PID is still the same.

Is there anything what clean resources or queues?

If i have two processes and different queue key, than both return error 43 in same time.






Test script:
---------------
I create repository on Github: https://github.com/h4kuna/msg

Expected result:
----------------
Passive waiting without awakened
