It happens on all platforms. I posted an example which can be seen in 
the 'scrubbed html' at

I provide a description of the primary typical solution that is used at: 
Basically you don't directly invoke global operator new but instead use 
either a redirecting macro or use a custom version of new which takes an 
argument which identifies the heap you are targeting (possibly even 
single one for all of WebKit).

I can understand that some developers who have spent a lot of time 
developing monolithic desktop or server software are used to using the 
built-in global operator new. The concept of controlling memory like I 
am proposing is the rule in commercial library development and not the 
exception. I humbly ask that the WebKit team consider migrating towards 
this type of development. It will make WebKit considerably stronger 
outside the desktop market, and yet is rather easy to apply. It's 
largely a matter of accepting an idea that is a little different from 
what some have done in the past.
