    <p>Threads would not help. If you must give up on finding the leak, then the only solution to contain its effect is running a new <em>process</em> once in a while (e.g., when a test has left overall memory consumption too high for your liking -- you can determine VM size easily by reading <code>/proc/self/status</code> in Linux, and other similar approaches on other OS's).</p> <p>Make sure the overall script takes an optional parameter to tell it what test number (or other test identification) to start from, so that when one instance of the script decides it's taking up too much memory, it can tell its successor where to restart from.</p> <p>Or, more solidly, make sure that as each test is completed its identification is appended to some file with a well-known name. When the program starts it begins by reading that file and thus knows what tests have already been run. This architecture is more solid because it also covers the case where the program <em>crashes</em> during a test; of course, to fully automate recovery from such crashes, you'll want a separate watchdog program and process to be in charge of starting a fresh instance of the test program when it determines the previous one has crashed (it could use <code>subprocess</code> for the purpose -- it also needs a way to tell when the sequence is finished, e.g. a normal exit from the test program could mean that while any crash or exit with a status != 0 signify the need to start a new fresh instance).</p> <p>If these architectures appeal but you need further help implementing them, just comment to this answer and I'll be happy to supply example code -- I don't want to do it "preemptively" in case there are as-yet-unexpressed issues that make the architectures unsuitable for you. (It might also help to know what platforms you need to run on).</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
