Airspace Structure; Procedure
While thermalling at 3;800 FT MSL above TSA glider port South of DFW in Class E airspace two airliners became closer than I felt safe.  Exact distance was hard to judge maybe under 1/2 mile. The two airliners were very close behind each other. DFW Approach should consider that the largest glider port in the country is located just south of DFW Class B and should be cautious with airliners in this location.
Glider pilot reported NAMC events involving two air carrier aircraft inbound to the DFW area; the reporter suggesting more positive ATC separation procedures.
