Reformatting 1st post.
AMD FX-8150 8 cores, 3.6GHz (same as bb.pgr.jp's buildslave)
* threading (trunk)
50s to 59s (unstable), with -sv
48s to 58s (unstable), with -q
* multiprocessing
36s -sv
35s -q
* Considerations:
- Need the switch "--enable(disable)-mp"?
- [Win32] MP is disabled. Starting MP's subprocess takes several seconds, due to pickling instead of fork().
- [Win32] MP cannot be invoked via utils/llvm-lit. Investigating.
