Yes I had a look, and it doesn't fit imho:
1/ leveldb is c++ while for all our get*ent functions are in libc and needs=
 to
acees the db files.
2/ leveldb is really huge compare to tinycdb.


Btw: an unexpected gain of cdb is that for services for example the size of=
 the
db is greatly reduces from 2M to 800K here, doesn't matter much but it is c=
ool
:)
