[mythtv] mthfrontend leaves processes behind

[Dag Nygren]

Hi,

I have for a long time been struggling with multiple mythfrontend
processes popping up (no more than two at the same time though).
Now I decided to take alook et the "extra" process and conncted to it with
strace. 
And lo and behold: the process finished immediately when the connection
was made.

The trace looked like this:
[root at tv i386]# strace -p 8774
Process 8774 attached - interrupt to quit
close(18)                               = 0
close(19)                               = 0
shmget(1236, 32768, IPC_CREAT|0666)     = 17956900
shmat(17956900, 0, 0)                   = 0xb11cf000
mlock(0xb11cf000, 32768)                = 0
shmdt(0xb11cf000)                       = 0
shmctl(17956900, IPC_64|IPC_STAT, 0xb36998b0) = 0
unlink("/tmp/alsa-dmix-8449-1136639790-226688") = 0
shmdt(0xb5673000)                       = 0
shmctl(17924131, IPC_64|IPC_STAT, 0xb36998b0) = 0
semctl(229376, 0, IPC_64|IPC_RMID, 0xb36998e4) = 0
exit_group(0)                           = ?
Process 8774 detached

What does this indicate?
The extra process has a PPID of 1.
Orphaned process?
