The designers of System V IPC considered resource leakage to be a feature.

POSIX semaphores are much nicer. The Linux manual page of sem_destroy has
this to say:

# An unnamed semaphore should be destroyed with sem_destroy() before
# the memory in which it is located is deallocated. Failure to do this
# can result in resource leaks on some implementations.
