[texhax] TeX capacity and hyperref

[Karl Berry]

    ! TeX capacity exceeded, sorry [pool size=67355].

That is quite a small pool size.  Nowadays the default is more like
1,200,000.  You can alter this by changing pool_size in
<texmf>/web2c/texmf.cnf, or setting pool_size in the environment (I
think; not sure if you have to redump .fmt's).

    Question: is there a way to convince hyperref to clean up from time
    to time, like \clearpage does for floats ?

That I don't know, sorry.
