Looking forward to it!

But..

Sorry to say, but it looks like I spoke to soon regarding the memory usage 
patch for plzip 1.6.

Continuing with some custom scripts related to slackware package conversion 
(nothing official, just personal stuff), plzip 1.6 with the latest patch (I 
think of it as the '3GB patch') was throwing errors on my i7 about running out 
of memory. Oddly enough running identical tests on an identical data set would 
sometimes succeed, sometimes fail, or sometimes say it succeeded but silently 
fail. Very weird. Reverting to unpatched plzip 1.6 & restoring the thread 
limiting loop in my scripts gave me predictable/desirable results.

Essentially, I *think* the patch originally worked by accident on my somewhat 
odd hardware/software combination. Only by having a larger (very time 
consuming) data set did I spot this.
