I am curious about getting a more recent version of v8 running in either node 0.7.x or 0.6.x.
I tried swapping out v8 in 0.7.8 and 0.6.17 with a copy of v8 3.10.8.4 (checking and applying any of node's floating patches on v8) and everything seems to compile fine and at least work somewhat, but it always segfaults at the end (of the first tick?). Maybe I'm missing other floating patches or changes? Specifically I checked changes/patches made to v8/SConstruct, v8/tools/gyp/v8.gyp, and v8/build/common.gypi.
