Non deterministic command line

[Martin J. Logan]

Hello all, 
  I have run into something a little strange with regard to erlang
command line env vars. I noticed that passing command line environment
variables to a node results in a non-deterministic sort and store for
the env vars. Example:

 -galaxy_parser is_failover_enabled true"
. 
.
.
 -galaxy_parser galaxy_feed_port ", TickerPort, 
 -galaxy_parser galaxy_feed_IP localhost", 
 -galaxy_parser galaxy_timeout infinity ",
 -galaxy_parser is_failover_enabled false"

results in is_failover_enabled being false

while                  
 .
 .
 .
 -galaxy_parser is_failover_enabled true"
 -galaxy_parser is_failover_enabled false"
 -galaxy_parser galaxy_feed_port ", TickerPort, 
 -galaxy_parser galaxy_feed_IP localhost", 
 -galaxy_parser galaxy_timeout infinity ",
 
results in is_failover_enabled being true.

Why is this. A deterministic order would make a few things nice and easy
for me right now because I need to count on what overrides what. 

Cheers,
Martin
