By 'not a bottleneck', I assume you mean "runs quickly"?  If so, I'll
run GetCurrentThreadId() in a tight loop and see how many invocations
per second I can get.

To the rest of the maintainers, pending the above two changes, is it
ok to commit?

Also, does anybody know how to use autoconf to test if the *linker
invoked by gcc* is GNU ld >= 2.3.x?  I don't believe it's possible to
test for this, but if it were, I could undef
JV_LINKER_CANNOT_8BYTE_ALIGN_STATICS for people who have a recent

I'll also add a comment indicating that
JV_LINKER_CANNOT_8BYTE_ALIGN_STATICS is not required for GNU ld >=
