jemalloc consistent use of bool?...

[Paul Pedriana]

While tracing through the jemalloc source code, I noticed that it seems 
to use bool inconsistently with respect to success/failure. Sometimes 
true means success and false means failure, while other times it's the 
reverse. For example, the prof_dump_flush function returns true upon 
success and false upon error. But the malloc_init_hard function returns 
false upon success and true upon failure. There appear to be cases of 
functions acting both ways. Or am I misreading the code?

Thanks.
