Yes. It appears to be working fine.

I don't have any special preference. I noticed that the pid file 
implementations in other daemons (within lvm2) don't use it nor unlink 
the pid file on exit.

Works for me.

I am going to make it a lib call and cleanup both cmirrord/dmeventd/clvmd.

Do you have anything against atexit() handler? That's what we use in 
cluster daemons to unlink the pid files.
