Are you sure 1.2.27 resulted in no hangs for you?  I had tried 1.2.27 before (ebuild) and got hangs (but before I had this testsuite), and I just now downloaded 1.2.27 from oss.oetiker.ch and compiled it, and now I *do* get hangs.

And just like before with 1.2.27 I am seeing a memory leak, slowly consuming more and more memory.

Here's the output from the script for 1.2.27:
