TSVNCache memory leaks

Hi there,

some days ago, a coworker had TSVNCache go berserk and
finally eating 3GB of memory (x64). That gave me sufficient
motivation to search the code for improper memory management.

r15974 fixes a number of obvious ones and I merged that code
also into 1.6.x. r15975-7 try to make other parts more robust.

Since TSVNCache is notoriously hard to test, it is very possible
that I broke something. If you encounter any problem with the
next nightlies, please tell us.

Stefan, could you review my changes?
