 DragonFly BSD supports Amiga @-@ style resident applications feature : it takes a snapshot of a large , dynamically linked program 's virtual memory space after loading , allowing future instances of the program to start much more quickly than it otherwise would have . This replaces the prelinking capability that was being worked on earlier in the project 's history , as the resident support is much more efficient . Large programs like those found in KDE Software Compilation with many shared libraries will benefit the most from this support .
