Public bug reported:
By default libguestfs will register an atexit() handler to cleanup any
open libguestfs handles when the process exits. Since libguestfs does
not provide any mutex locking in its APIs, the atexit handlers are not
safe in multi-threaded processes. If they run they are liable to cause
memory corruption as multiple threads access the same libguestfs handle.
As such at atexit handlers should be disabled in any multi-threaded
program using libguestfs. eg by using
guestfs.GuestFS (close_on_exit = False)
instead of
guestfs.GuestFS()
