These builds have debugging info inside. That means you can debug a
server and see what the actuall code that runs it. It also mean that if
it crashes, you can read where in source code it happened (as apposed to
machine code).

Probably won't help you directly :) But it will help FB developers if
you send them core files or simple backstrace (stack of function calls
that lead to it).

Yes. However there is some performance penalty (the executable is much
bigger, and some compiler optimizations are turned off since it would
loose the binding with source).

Try it. If it runs fast enough, you can use it without problems.
