Subject: hash *needs* rehashing?

I'm using hashes intensively in an archive module.  Often h['foo']
returns nil, although `p h shows that value corresponding to 'foo' is
there.  If I do a f.rehash before accessing the value, everything
works as expected.

So, what is happening here?  Do hashes release their `map' under
certain condition, and it needs to be remade by rehashing?

I'm not attaching a snippet because I've not been able to reproduce
this outside the current code, which is too long to post here.
