Unload library

Hi Developers,

[ The Context ]

I have a small project that use DLL libraries from external origins (I
can´t access to the sources codes). currently I´m using jruby’win32ole
with a great results but … I found a memory leak in one of the
libraries and I need to remove this library (and reload again later)
when the consumed memory arrives a defined limit.

[ The Question ]

Is possible to UNLOAD a native dll library in jruby/ruby?

Thanks in advance for your responses
Have a nice code !
