New issue 1859 by [email protected]: v8 is full of static initializers
http://code.google.com/p/v8/issues/detail?id=1859
On Mac, we're down to 47 files with static initializers (not counting the
ones created by protobuf). 23% of these – 11 filles – are caused by v8!
Mac List:
assembler.o
code-stubs-ia32.o
frames.o
isolate.o
lithium-allocator.o
log.o
platform-macos.o
platform-posix.o
runtime-profiler.o
v8.o
logging.o
The linux output is a bit more detailed (the linux compiler is also a bit
more stupid and needs static initializers for more stuff), it's v8-related
output is:

Please fix :-) Static initialization delays startup by up to 500ms on some
platforms.
In chrome land, we had success with base/lazy_instance.h (make them leaky,
so that they don't require exit time shutdown).
