use of IvyContext

[Peter Reilly]

Hi,
I have been tracking a memory leak
(http://issues.apache.org/bugzilla/show_bug.cgi?id=42742)
and found an issue with oai.core.IvyContext.

IvyContext.setIvy(Ivy) is used in Ivy#bind(),  will this
not wipe out the current Ivy setting in a multi-project enviroment?

i.e.
  Project A:
      IvyContext.setIvy() (ivy in project A)
      ant call -> Project B
           IvyContext.setIvy() (ivy in project B)
           .endProject B
      .. back in project A
      .. here IvyContext().getIvy() will return ivy from project B.
      ant call -> Project C
           IvyContext.setIvy() (ivy in project C)
           .endProject C
      .. back in project A
      .. here IvyContext().getIvy() will return ivy from project C.
