I have same issue. Ongoing for more than 1 year and currently running iTunes 11.3.
My PC is Dell OptiPlex 990 I7 processor, 8GB ram, W7 64 [always keep things patched up to latest OS updates etc]
I use this iTunes install to stream music videos etc to multiple appleTVs, ipads, iphones etc .. via Home Sharing
Store all my media including music, videos and apps on separate NAS  .. so the iTunes running on PC is only doing the traffic cop role and streaming / using files stored on NAS .. creates lots of IO across my network
Previous troubleshooting suggest possible contributing causes include
a) podcast updates  .. until recently I had this auto updates on multiple podcast subscriptions, presumably the iTunes would flow this from the PC to save on the NAS across the network .. if the memory leak is in the iTunes network communication layer (?bonjour?)  this may be sensitive to IO that would not normally occur if the iTunes file saving was local on the same PC
b) app updates .. have 200+ apps in my library and there is always a batch of updates .. some updates 100s of MB is size .. routinely see 500MB to 1GB of updates in single update run .. all my apps are
c) streaming music / movies .. seems when we ramp up streamlining of music or movies . memory leak grows faster .. ie within hours of clean start
c) large syncs of music or videos to ipads or iphones .. noticed that get big problems when I rebuild an ipad .. I typically have 60+ GB of data in terms of apps /  music / videos to load .. have to do rebuild in phases due to periodic lockups
