[R] Large loops hang?

Dear useRs,
Suppose we have loop:
res <- c()
for (i in 1:100000) {
x <- rnorm(2)
res <- c(res,x[2]-x[1])
}
and this loop for 10^5 cases runs about - for example 5 minutes.
When I add one zero (10^6) this loop will not end overnight but probably
hangs. This occurs regardless of calculated statistics in such
simulation, always above 10^5 times. Nested loops do not help.
Any suggestions for collecting larger amount of Monte Carlo data ?
Regards
