I think this is the same issue that was reported here for timer_create
(which also has a helper thread):

  libc timer_create with option SIGEV_THREAD system call having memory
  leaks after timer_delete system call
  <https://sourceware.org/bugzilla/show_bug.cgi?id=29705>

I don't think there is a good way to fix this.  It's not an unbounded
leak, so it does not impact the application while it runs.

Thanks,
Florian
