The slave doesn't "turn off" the master. The trigger file is intended to be touched _when the master is down_.
Since the master never WENT down (or came back up) and the trigger file was touched, the slave got promoted.
You'll need to stop the slave, run your select pg_startbackup(), rsync, etc to get your slave back to slave mode.
There IS a trigger file, which does appear to have been "touch"ed. But the problem is that a fail-over hasn't really occurred since the original read/write primary continues to be a fully functioning read/write machine. But it's no longer replicating to the erstwhile standby, which has become read/write. Bottom line, I now have 2 read/write machines, but with no replication between them.

Sounds like you might have a "trigger_file" set in your recovery.conf. Do you? That or someone is issuing a pg_ctl promote command.
I'm using PostgreSQL 9.2.4 on x86_64-unknown-linux-gnu, compiled by gcc (GCC) 4.1.2 20070115 (SUSE Linux), 64-bit.
I set up streaming replication for a read/write primary and a read/only standby. The replication works fine for a while, and then out of the blue BOTH machines become read/write, but with no replication from the original primary to the newly read/write standby.
The only log entry that seems relevant is as follows: FATAL,57P01,"terminating walreceiver process due to administrator command",,,,,,,,"ProcessWalRcvInterrupts, walreceiver.c:150",""
Any help/guidance would be appreciated. Thanks in advance.
