Nice, I've rebuilt pkg(8) against patched libarchive, and run `make
package' for devel/llvm40:
$ make
...
$ time make package
===> Building package for llvm40-4.0.0_2
2029.111u 6.614s 11:03.25 306.9% 7884+502k 4+2240io 1pf+0w
$ xzcat -t llvm40-4.0.0_2.txz ; echo $?
0
It went down from ~50 minutes to eleven on a 4-core APU. I've filed an
