Summary: Occasional SEGV in flatstore flat_db_insert

Initial Comment:
The flat_db_insert function currently grabs the file handle from the db connection *before* performing file rotation.  This works most of the time because the underlying fopen() returns the same address in the FILE *.  Sometimes, however, the address changes. In that case, the file handle grabbed is invalid, and either the next record does not get written, or in some cases, it actually crashes the server.

Taking the FILE * after rotation cleared up a big headache for me in my 1.1.1 installation.  It still seems applicable in HEAD.  Attached is a patch against HEAD that does it.  I believe it fixes the problem described in:
