I wan't to get rid of the backspace that SGE is printing.
Here's something I came up with, as a proof of concept for
getting rid of the backspace, which relies on the fact that
printf doesn't care if it had more arguments than it does
placeholders in the format string.
You thus simply write the word INFINITY out where you need
it and stick in the platform specific int placeholder
elsewhere.
Note that this PoC explicity sets the resource to query
RLIMIT_DATA
and sets the "max" of that,
dlp.rlim_max
to the "infinity value" for testing.
