/* Sigh.
* Valve compiled Steam against the glibc2.2 version of setrlimit.
* This broken version aliased 0 to RLIM_INFINITY.
*
* So, what you have to do is: if you want to run steam with this gcompat,
* ensure you compile *without* defining NO_BROKEN_SHADOW_SETRLIMIT.
* If you do *not* want to run steam with this gcompat, define it.
*
* The only problem with enabling this all the time is that if a binary
* really does need a ulimit to be 0 for any reason (such as coredumps), it
* very obviously won't work here.
