Subject: [PATCH] Create the flush thread on first use

Some processes just return from the entry point; this only exits the
thread, not the process.  It seems that when ANSICON created its flush
thread in DllMain, that became the primary thread, so when the entry
point returned the process was still waiting for the flush thread to
exit.  Creating the flush thread the first time it is used avoids this
problem, letting the process exit.
