Disabling program core dumps

[Willem Jan Withagen]

Hi,

Running (googletest) tests some are expected to die: EXPECT_DEATH().
This normally dumps a core, but since it is expected that core is rather
useless.

Thusfar I've found the best way to limit a program to dump core (from
within the program) is to set its RLIMIT_CORE to 0.

So I can do this before the test, and then set the old size back once
the test is finished.

Or is there another way, like setting a flag in process state (which I
have not been able to find)
