The mnemonic should be LD_NOSHADOW_IF_YOU_CAN.
The option only work if the Shadow group *has* his owm 0x0000 element.
(that contains le group length; gdcm is able to skip the whole group, 
and save parsing time.
If the 0x0000 element doesn't exist, gdcm has to parse each element, 
and it would take more time to erase them.

--> Same behaviour with LD_NOSEQ (works only with 'true length 
sequences', doesn't work with 'no length Sequences')
