The flags exist, but in the adage of the lazy programmer, "less
keystrokes, means less RSI/bugs."   One nice option would be for R to probe
the size of the .RData file, and rather than dieing on you if it's too
large, giving you option of loading it with XX extra memory.

This is always going to be the case since R uses a static memory heap.
So the question arises; if the default is 15, why not 20...? 

The best solution would be for system wide config flags or ENVIRONMENT
variables, as this would allow people to set a memory usage policy given
the amount of library functions they have, general memory usage patterns,
and personal inclinations.
