My main concern was to avoid the memory leak.

We can add parameters to Carpet, use them from thorn timers, and add warnings if they are set. Are there volunteers for this work? I feel that I deserve a break after fighting the Intel compiler for a week, and adding parameters and warnings doesn't require the deep understanding of Carpet that tracking down memory leaks does. (I want to re-emphasize that the code was fine, this memory leak was (probably) a problem with the Intel compiler, and the current code only contains a work-around to avoid the problem, it doesn't "correct" the problem.)

We can also make thorn Timers optional, probably either by sprinkling (and there will be many, probably more than a hundred) #ifdefs, or by introducing wrapper classes around all the Timers classes in all thorns that want to optionally depend on Timers. Neither is ideal...
