   @wu-sheng, I would definitely like to implement support for Vert.x so if 
it's necessary to create a new TracingContext implementation to do that then 
yes, please start a draft.

that.
   
   Before you do, would you mind breaking down a bit why a new implementation 
is necessary? Specifically the logic quoted above. I understand a span to be a 
single "unit of work". From the SkyWalking documentation a segment is "a 
concept in SkyWalking, it should include all span for per request in a single 
OS process, usually single thread based on language". Based on these 
definitions, wouldn't everything involved with finishing the request for 
`/products/test` be included in the segment? Meaning why not add logic which 
indicates that a segment is always equal to or longer than the duration of the 
spans which it consists of?
