    <p>I'm currently using Retlang for message-based multithreading in .NET, which is a great library. I've got no explicit locks anymore, every thread is doing its own business, managing its part of the application and communicating with other threads via messages.</p> <p>I now have to implement a feature of my application that could also have its own publisher/subscriber thread. The only problem is that this thread will actually do very few work. It's expected to receive a message from a publisher every 10 minutes or so. When a message is received, it will do some work but nothing that should take more than a few hundreds milliseconds.</p> <p>So I started wondering if having a thread sleeping 99.9% of the time was actually a good choice. There's the thread pool for this kind of operation but since I have no control over which thread my messages will be received, I have to resort to ugly, error-prone locks.</p> <p>My question is: is it really a problem, resource-wise, to leave a thread idle, waiting the vast majority of time? Using shared multithreading after using a good message-based architecture feels like going back in time, plus it will be the only part of the application with locks. But I keep wondering "Am I doing something wrong here?" with this thread.</p> <p><strong>Edit</strong>: thank you everyone, after reading every of your answers I decided that another thread wasn't so much a problem. My application will stay coherent with only message-based multithreading and if I really have a performance problem (but that shouldn't be the case) I'll investigate further.</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.
