sem_get error

run the load from the user on the dev box like
```
manticore-load \
--batch-size=1000 \
--threads=4 \
--total=10000 \
--load="INSERT INTO test:t2(idd,tag,f1) VALUES(,,'')"
```
I got the following error
```
======================================================================================
Process 1: Running with threads=4, batch-size=1000

Warning: sem_get(): Failed for key 0x6f030052: Permission denied in /usr/share/manticore/modules/manticore-load/console_output.php on line 33
Failed to create output semaphore
```

run from the sudo works fine

Reproduce the reported command as a non-root user and compare it with the sudo run. Start at modules/manticore-load/console_output.php line 33, where sem_get() reports permission denied and output semaphore creation fails. Done means the non-root invocation no longer fails, or the issue clearly documents the required permission behavior.
