> The lifetime of Request objects is tied to the worker thread(s) in the async 
> event loop.  In the current code there's nothing that prevents a request from 
> outliving the RpcEngine (bound to FileSystem) while it's waiting for IO.  If 
> the Request, or a task that makes a new request, outlives the RpcEngine it 
> attempts to dereference a dangling pointer and either crashes or continues to 
> run with bad data.
> Proposed fix is to reference count the RpcEngine via shared_ptr so that 
> Requests can hold a weak_ptr to it.  When a request or RpcConnection 
> attempting to make a request needs something from the RpcEngine like a call 
> id number it can promote the weak_ptr to a shared_ptr.  If it's unable to 
> promote because the RpcEngine has been destroyed the Request's handler can be 
> invoked with an appropriate error message.  A weak_ptr must be used rather 
> than a shared_ptr to avoid reference cycles.

> event loop.  In the current code there's nothing that prevents a request from 
> outliving the RpcEngine (bound to FileSystem) while it's waiting for IO.  If 
> the Request, or a task that makes a new request, outlives the RpcEngine it 
> attempts to dereference a dangling pointer and either crashes or continues to 
> run with bad data.
> Proposed fix is to reference count the RpcEngine via shared_ptr so that 
> Requests can hold a weak_ptr to it.  When a request or RpcConnection 
> attempting to make a request needs something from the RpcEngine like a call 
> id number it can promote the weak_ptr to a shared_ptr.  If it's unable to 
> promote because the RpcEngine has been destroyed the Request's handler can be 
> invoked with an appropriate error message.  A weak_ptr must be used rather 
> than a shared_ptr to avoid reference cycles.
