> Why isn't it masking before writing to disk ?

Crash handlers don't know what state the system will be in when they're called. Will we be completely out of memory, so even malloc calls have started failing and no library is safe to call? Are we out of disk space, so we maybe can't write our logs out anyway? Is storage impaired, so we can write but only incredibly slowly? Is there something like a garbage collector that's trying to use 100% of every CPU? Are we crashing because of a fault in our logging system, which we're about to log to, giving us a crash in a crash? Does the system have an alarm or automated restart that won't fire until we exit, which our crash handler delays?

It's pretty common to keep it simple in the crash handler.
