Description

=begin
1.9 では sleep で寝ているスレッドを Thread#run で起こせない
ようです。

% ./ruby -ve '
t = Thread.new {
t1 = Time.now
sleep 5
t2 = Time.now
p t2 - t1
}
sleep 1
t.run
t.join
'

sleep を Thread#run で起こせるっぽいことは rdoc に書いてありま
す。

  • Suspends the current thread for duration seconds (which may be any number,
  • including a +Float+ with fractional seconds). Returns the actual number of
  • seconds slept (rounded), which may be less than that asked for if another
  • thread calls Thread#run. Zero arguments causes +sleep+ to sleep
  • forever.

また、1.8 では起こせます。

% ruby-1.8 -ve '
t = Thread.new {
t1 = Time.now
sleep 5
t2 = Time.now
p t2 - t1
}
sleep 1
t.run
t.join
'
