/*
* SQLite and the JDBC API have very different ideas about the meaning
* of auto-commit. Under JDBC, when executeUpdate() returns in
* auto-commit mode (the default), the programmer assumes the data has
* been written to disk. In SQLite however, a call to sqlite3_step()
* with an INSERT statement can return SQLITE_OK, and yet the data is
* still in limbo.
*
* This limbo appears when another statement on the database is active,
* e.g. a SELECT. SQLite auto-commit waits until the final read
* statement finishes, and then writes whatever updates have already
* been OKed. So if a program crashes before the reads are complete,
* data is lost. E.g:
*
* select begins
* insert
* select continues
* select finishes
*
* Works as expected, however
*
* select beings
* insert
* select continues
* crash
*
* Results in the data never being written to disk.
*
* As a solution, we call "commit" after every statement in auto-commit
* mode.
