Compile at -O2 and disable optimizations that trigger gcc bugs.
Some people still reported mksnapshot crashes after commit b40f813 ("build: fix
spurious mksnapshot crashes for good" - so much for that).
Average performance of the -O2 binary is on par with the -O3 binary. Variance
on the http_simple bytes/8 benchmark appears to be slightly greater but small
enough that the possibly of it being noise cannot be excluded.
The new binary very slightly but consistently outperforms the -O3 binary (by
about 0.5%) on the mostly CPU-bound bytes/102400 benchmark. That could be an
artifact of the system I benchmarked it on, a Core 2 Duo with a puny 32 kB of
L1 instruction cache. The smaller binary seems to play nicer with the cache.
The v8 team apparently decided that all build products should go
into ./build/«type», and updated their common.gypi file to do so.
Unfortunately v8's common.gypi is only used for some targets. All
the other targets would still look in the old place to find their
their dependencies, which effectively broke the build.
In the long run it would be good for node to send all build
output to ./build too, on all platforms.
The old error handling code checked if the return value of Socket::Send() != 0,
which is wrong because Socket::Send() can write less bytes than requested or
return -1 on error.
