[R] Suspected memory leak with R v.2.5.x and large matrices with dimnames set

Hi - Admittedly, this may not be the most sophisticated memory profiling performed, but when using unix's top command, I'm noticing a notable memory leak when using R with a large matrix that has dimnames set. To allow people to reproduce the problem I'm seeing, I've

Seth's analysis is correct. R does return what it can to the malloc system by calling free. When and how much memory malloc releases back to the OS varies with OS and malloc system and also depends on the sizes of allocations. R curently allocates its memory for small objects in pages of about
