You obviously haven't been reading the news:

Google's new web browser Chrome is written in C++. A buffer overrun security
vulnerability was found in it 6 days ago:

Avoiding heap fragmentation in concurrent C++ was a major problem for
Google:

I'm a bit skeptical about the claim that heap fragmentation can be a
significant problem in a web browser.

My cynical guess is that Google realized that their browser was so
prone to crashes and glitches that they decided to split it in several
processes as a form of "damage control".

Heap fragmentation has been a headache for Mono since its inception:
