Description

[ 1 paragraph concisely describing the bug ]
The NotifReceive function is blocked and the notifHandler goroutine cannot exit.
When the container generates a new process, seccomp agent will allocate a notifHandler goroutine to monitor the abnormal syscall. When the process was dead, the notifHandler goroutine was still there and blocked at the NotifReceive function.

Impact

A large number of useless notifHandler goroutines are generated in the seccomp agent container
