Thanks.
I've done some changes. Now the code seem to work, but about 2-3% of 
memory is not cleared. Example:
Before create 1000 hairs: 160 MB
After create 1000 hairs: 170 MB
After delete the hairs: 163 MB


The code now is:

def deleteHairs():
     global objHairs
     sc = Scene.getCurrent()
     for ob in objHairs:
         obData = ob.getData()
         obData.verts=[]
         obData.faces=[]
         obData.update()
         sc.unlink(ob)
     sc.update(0)
     objHairs = []


Thanks!
