Determining if process is alive on a different node

[Joel Reymont]

Folks,

I have a pid but I don't know if it's a local one. How would I  
determine if the process is alive?

I'm storing pids in a Mnesia table in a multi-node environment and  
the node that hosted the process might have died. Rather than  
tracking node crashes I was wondering if there was an idiomatic way  
of figuring out if a process is alive.

My understanding is that I can only use is_process_alive for local  
processes.

     Thanks, Joel
