Forgot to add: to reproduce, remember to provide --enable-__cxa_atexit at build

Sorry, actually I meant around 25%, rather troublesome, anyway... Frankly,
I don't know where the slowdown comes from, we should profile the testcase for
both the allocators. These are some numbers on my P4-2400:

Yep I'll add this to my other tests (insert-thread) to profile today, thanks
for the pointer.
Can I close this out? I believe this is fixed, no?

I think that is a bug in the front-end:
:;
if (__priority == 65535) goto ; else goto ;
:;
if (__initialize_p == 0) goto ; else goto ;
:;
__comp_dtor (&idl_filename);
:;
if (__priority == 65535) go

Ah, the problem is, that for some reasons GCC emits _two_ dtor functions
for 'idl_filename' (__tcf_2 and __tcf_1), but only if the extern decl comes
after the definition. Okay, this is an error in itself, but it seem
