RequestHandler lifecycle in a Multiple SolrCore context

[Kay Kay]

If I have a CustomRequestHandler that inherits from RequestHandlerBase 
implementing SolrCoreAware interface - what is the lifecycle of the 
invocation of method - inform(SolrCore) in a multiple SolrCore context .

Would it be that we have separate instances of RequestHandlers created 
for each SolrCore.

Can somebody add more information about the same.
