. Add fix for "runaway process" problem. It should fix of stalled

  processes problem for people who use Runtime.getRuntime.exec() method
  and related things.  Least five people reported that this patch fixed
  problem for them.

  IMPORTANT: I'd also suggested to all jdk14 users who runs FreeBSD 4.x
  and use libc_r at FreeBSD 5.x to upgrade.

. Stop removing "src.zip" from installation bundle.  Since -p4 it builds
  correctly and there's no reason to forbit people to use it.

. Bump PORTREVISION.
