Linux should already return "large" (greater than 128K) memory blocks back to the OS since (as discussed in Re: Not able to release memory) it should already be using glibc 2.x ptmalloc (based on Doug Lea's malloc). My experience with Solaris is that its system malloc never returns memory back to the OS. Do you see any difference in memory behaviour between Linux and Solaris?

    [choroba]: (well, it comes from the 14th century, so labelling it as "modern" doesn't seem appropriate)
    [Your Mother]: "They" is becoming accepted but it irritates me sometimes. I tend to just pick she or he randomly or try to use "one."
    LanX thinks it is appropriate here :)
    [Your Mother]: They would think so.
    [jdporter]: ok, I need a recipe for piping lines "through" an external program which is itself a filter
    [jdporter]: without using a tmp file
    [1nickt]: tobyink perl -MTypes::Standard= is_Int -Mstrict -wE 'say 1 if is_Int 1.0'
    [jdporter]: so that I can use the existing expand unix util. Otherwise, I'll probably use Text::Tabs.
    [1nickt]: pryrt I guess I don;t really care if user 42 logs on as 42.0 ... more of an academic question at this point.
    [LanX]: jdporter: open PIPE,'-|' ?
