-OpenBSD's new privilege revocation system call [http://www.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man2/pledge.2 pledge(2)] is based largely on the concept that programs do most of their privileged operations during initialization, eventually dropping into a main loop that is "boring and full of buffer overflows". The `pledge(2)` model therefore allows the process all privileges until it makes the system call. This is fundamentally different from approaches such as App^^Armors, which have a static privilege list stored outside the program that is always enforced.

 The `pledge(2)` model makes more sense for network programs like Pidgin and is easier to implement. In these cases, we trust the ''binary'' to not be malicious, but we don't trust the remote network entities it interacts with, and we don't trust the binary to protect us from them. Many other access control frameworks results attempt to protect the system from potentially malicious binaries, which can add complicating rigidity.
