1988 that may need to compute untrusted bytecode during their
1989 execution. By using pipes or other transports made available to
1990 the process as file descriptors supporting the read/write
1991 syscalls, it's possible to isolate those applications in
1992 their own address space using seccomp. Once seccomp is
1993 enabled via /proc/<pid>/seccomp, it cannot be disabled
1994 and the task is only allowed to execute a few safe syscalls
1995 defined by each seccomp mode.

2058 The Extended Industry Standard Architecture (EISA) bus was
2059 developed as an open alternative to the IBM MicroChannel bus.
2061 The EISA bus provided some of the features of the IBM MicroChannel
2062 bus while maintaining backward compatibility with cards made for
2063 the older ISA bus. The EISA bus saw limited use between 1988 and
2064 1995 when it was made obsolete by the PCI bus.
