[Libguestfs] how to clear <defunct> qemu-system-x86 processes

[cyliu7]

Hi all,

I have a long term running program which call libguestfs to check VM 
images. but i found that each time after i call guestfs_close(), the 
qeum-system-x86 process which is forked by libguestfs changes to 
<defunct> process.

as docs of guestfs_close said "This closes the connection handle and 
frees up all resources used.", so this is a bug or is there any other 
way to clear them.

thanks a lot!
