[R] Problem with data.frame and attach

I just encountered a problem in R that may easily be fixed: If one uses
attach for a data.frame e.g. 10000 times and forgets detach, then R gets
incredibly slow (less then 10% of the original speed).

My system:

platform powerpc-apple-darwin6.0
arch     powerpc
os       darwin6.0
system   powerpc, darwin6.0
major    1
minor    6.1
year     2002
month    11
day      01
language R

Kind regards,
Andreas Eckner
