So the horror Stories where about jemalloc. I though there were about 
libmalloc or something :)

In that case leaving it out will definately give us benefits if I get it 
right. Also jemalloc in Mozilla is not the upstream jemalloc and there 
were a lot of improvements there. There was some mention about TLS 
needing it. But if that does not apply then I would say disable it.

It would also be nice to check with Illumos mailing list to see how our 
malloc is different from FreeBSD and how this influences the situation. 
If I understand Brian Cantrill corretly our implementation knows what it 
should do and when it does not we should fix that instead of using 
something like jemalloc.
