If you haven't seen this. It's a must have.
I sure wish they'd provide an idea of the eventual cost, though. I can understand their not wanting to right now, but I at least can't afford to invest time into their beta program without knowing if I'll be able to afford it when they start charging for it.
I just posted the pricing information on the site. We haven't finalized the actual price yet, but we expect to price this product in line with typical quality and load testing tools (think low four figures, USD). We will definitely offer substantial discounts to those customers who help us during our beta by submitting bugs or issues they find with Jinx itself, or by submitting bugs they've found in other software (their own or open source) using Jinx. Visit our "Report a Bug" page to give us feedback.

As it turns out, the (reduced cost, I assume) non-commercial version will be just right for what I'm thinking of doing in this space. And of course I'll sing the praises of Jinx to the extent it helps me find the nasty types of bugs it's designed to.
Hmmm, one of the most interesting (at least to me) projects I'm thinking of in this space is a hypervisor based multi-threaded/core Appel-Ellis-Li garbage collector. It's based on marking pages unreadable to implement a read barrier and its preformance is very dependent on the speed of handing read traps, which is not something normal operating systems optimize since that's normally an error.
To allow concurrency, the GC itself has to live in the hypervisor or thereabouts, where it isn't barred from reading pages that are unreadable at the user level.
