	L Locker
	// contains filtered or unexported fields

func (*Cond) Broadcast

type Pool

type Pool struct {
	New func() interface{}
	// contains filtered or unexported fields

A Pool is a set of temporary objects that may be individually saved and retrieved.

GopherJS provides a simpler, naive implementation with no synchronization at all. This is still correct for the GopherJS runtime because:

  1. JavaScript is single-threaded, so it is impossible for two threads to be accessing the pool at the same moment in time.
  2. GopherJS goroutine implementation uses cooperative multi-tasking model, which only allows passing control to other goroutines when the function might block.

TODO(nevkontakte): Consider adding a mutex just to be safe if it doesn't create a large performance hit.

Note: there is a special handling in the gopherjs/build package that filters out all original Pool implementation in order to avoid awkward unused fields referenced by dead code.
