Currently the only active code that can return error is :
judy_bitset : : reset ( ) / J1U ( )
judy_bitset : : setbit ( ) / J1S ( )
In most cases errors are either about wrong parameters passed to Judy
functions or internal structures corruption . These definitely deserve
abnormal process termination instead of exit ( ) as it is done by original
JUDYERROR .
TODO : there ' s one exception that should be handled properly though : OOM .
