Bug 4909 Trap handlers should not be re-enterable?

From [ruby-dev:43852] trapハンドラは再入されてはいけないのではないか？

Ticket in redmine http://redmine.ruby-lang.org/issues/4909

Kosaki said, the following code shouldn't raise any Exception.

n = 0
intrap = 0

parent = $$

trap(:USR1) {
  if intrap == 1
    raise "trap nested"
  end
  intrap = 1
  10000.times {
    n += 1
  }
  intrap = 0
}

fork do
 Process.kill(:USR1, parent) while true
end

sleep 100

Problems are:

• You can raise stack overflow by throwing signal continuous (like this program).
• There is no signal blocking method; like sigprocmask() in ruby level, so we can't write good signal handlers in ruby.

He also said that C masks signal during running signal handler, so MRI should make same consideration as C.
