  make distclean
  CC=clang CXX=clang++ ./configure
  make

sysctl(CTL_HW, HW_PHYSMEM) always returns unsigned long. Will work fine for 32 and 64 bit systems. Closes #1233.

Using @bnoordhuis's punycode lib.

Fails a few tests

Due to downgrade of V8.

This reverts commit 3e2abd12.

Revert due to V8 downgrade.

This reverts commit 04c91698.

Too slow.

This reverts commit e7ac6d8f.

There are serious performance regressions both in V8 and our own legacy
networking stack. Until we correct our own problems we are going back to the
old V8.

Fixes #558.

Doing it the other way around means that V8 won't pick
up command line switches like `--prof`.

Props to Joshua Kehn for reporting the issue and Jeff Fifield
for pointing out the cause.

Fixes #900.
Fixes #1217.

Fixes #1276
