* page format.
* The tables you want to be automatically splitted when the page ends must
* have a class name of "splitForPrint" (can be changed).

ruby-oci8 Runtime Error "executing in another thread"
# This will trigger Runtime Error "executing in another thread" from ruby-oci8
# The cause is Timeout interrupted the rb_thread_blocking_region() and causing
# oci8_unblock_func() to be run, however, svcctx->executing_thread is not set
# to nil, causing the client to get into a bad state.
# See http://rubyforge.org/forum/forum.php?thread_id=50112&forum_id=1078
