nsIProcess spawns non block processes in a 'fire and forget' fashion. There doesn't seem to be a way of finding anything about it after it's spawned. 

nSIProcess.run() should return the pid of the process. But it returns 0 when the blocking flag is set to false. (try to run process in Non-Blocking mode)

nsIProcess.exitValue always returns -1 for a Non-Blocking process even though the process is running.

Reproducible: Always

Steps to Reproduce:
1. invoke the nsIProces.run with the blocking flag set to false
2. alert the return value.
3. Check the nsIProcess.exitValue periodically.
Actual Results:  
nsIProcess.run() returns zero and and nsIProcess.exitValue always returns -1

Expected Results:  
nsIProcess.run() should return the pid of the process and it should set the nsIProcess.exitvalue to -1 only after its terimination.
