Ironically, this was my first problem. First of all, I don't think I
want the semi-closed state -- I want to be able to read and write
freely later on (I may be misunderstanding semi-closed, however).
Second, when I used this approach, after the hGetContents call I did
the regexp matching, and the program hung during matching.
