apt uses up all memory and errors out during postinstall

[maphew]

Installing sip with apt the computer appears to hang during postinstall at the textreplace stage. Cpu usage is low, around 12%, and python.exe memory use climbs slowly but inevitably until it errors out tens of minutes later.

MemoryError

I've encountered this once or twice before but didn't pause to document it. I don't recall if it's always with the same package, or even always textreplace (a vague recollection of dll-dupes). Running textreplace manually on sipconfig.py.tmpl from o4w shell returns in seconds.

Host system is win7x64. Same results with apt from svn and package.

I was not reading the output carefully enough, textreplace was the last SUCCESSFUL command. The real problem was infinite regex recursion in def postinstall(). Fixed in r1156.
