Subject: SQLite is rather peculiar on disconnection as described at http://www.perlmonks.org... 
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=5b8cee5c4a675888bc531aee20326cc2100721b6;p=dbsrgits%2FDBIx-Class-Historic.git

SQLite is rather peculiar on disconnection as described at perlmonks.org/?node_id=666210. Add an ugly workaround to Storage::DBI, and add a TODO test to detect if the problem is resolved
