Description

The following sequence is currently broken : 

hDS = GDALOpenShared("foo.tif", GA_ReadOnly); (done in thread T1)
GDALClose(hDS); (done in thread T2) --> doesn't remove hDS from the set of shared dataset
hDS = GDALOpenShared("foo.tif", GA_ReadOnly); (done in thread T1) --> returns previous pointer on destroy object...
GDALGetDescription(hDS); --> crash or big Valgrind warnings
