Maybe, maybe not. For one thing, it's always advisable to have dedicated disks for swap. Also, when more than one process is using the text (instructions) or read-only data pages in question, they are much less likely to be abandoned. The extensive use of shared libraries means that many of the potentially sharable pages within a given process are likely to actually be in use by other processes, as well. Only large applications tend to have a high ratio of unique to shared pages. > -- > Cheers, > Carlos E. R.
