Why chromium does not use c++ exception safety mechanism.

[kapil2905]

Hi,

I tried using a try-catch block in chromium code and the build failed after it.
I found out that try-catch mechanism is not used at all in chromium.

[1] Why is it so ?
[2] Is this only for performance gains ?
[3] If [2] is true, then how exactly performance is improved by avoiding
exception safety mechanism ? Maybe by avoiding some extra function calls.
[4] What are the scenarios where it is advised to avoid exception safety
mechanism ?

Thanks for any inputs :)
