Management of the audio interface is notoriously bad in Goog Chrome, so we've all adopted the same ritual in the 15 years since the Goog's IPO.

Then, you have to run ipcs & ipcrm to delete all the IPC objects it leaves behind, one by one.  Goog employees don't know how to properly delete shared memory when their programs crash.  For those of us not completely focused on passing interview questions with leetcoding, the secret is to call 

shmctl(shmid, IPC_RMID, 0);

right after calling 

shmat(shmid, NULL, 0);

But anyways, it was finally time to automate this process.

This program just deletes every IPC object.  It has to be run as root.
