 lispy/cale confirmed behavior, and cale suggested fix: 

{{{
 <lispy> patch-tag:  http://www.haskell.org/ghc/docs/6.10.4/html/libraries/unix/src/System-Posix-User.html#getAllGroupEntries


<Cale> getAllUserEntries =

<Cale>     withMVar lock $ \_ -> bracket_ c_setpwent c_endpwent $ worker []

<Cale> getAllUserEntries is properly bracketed

<Cale> getAllGroupEntries = withMVar lock $ \_ -> worker []

function has changed from 6.10.4 to 6.12 but I'm not sure if this fixed the bug:

 * 6.10.4: [http://www.haskell.org/ghc/docs/6.10.4/html/libraries/unix/src/System-Posix-User.html#getAllGroupEntries]
 * 6.12: [http://hackage.haskell.org/packages/archive/unix/2.4.0.0/doc/html/src/System-Posix-User.html]
