Many inner loops altered to make just 1-2 system calls rather than 4-5.
You can easily see how wasteful the previous code was, and find the culprits,
by patching r/o java.io.File methods and adding to -Xbootclasspath/p (or use AspectJ). E.g.:

public boolean isDirectory() {
  System.err.println("isDirectory: " + this); if (Math.random() < .01) Thread.dumpStack();
  // as before...
}

Ant still makes an order of magnitude more system calls to do what seem like simple operations
than you would think necessary, but this patch should at least improve the situation.

Unfortunately this is not the only place in Ant where List.contains is called;
DirectoryScanner.processIncluded seems to be as bad.
Alas, someone long ago made protected Vector fields in DS, and it seems too late to change them now:
even changing to ArrayList would break subclasses like FTP which call addElement!
