Seemed OK at first but:

- Include file completion doesn't work (you're probably already aware of this)

Biggest issue thus far is 100% CPU and memory exhaustion. Before indexing, TheIDE uses around 50 megabytes, after first indexing it goes up to around 150, then eventually libclang breaks, autocomplete stops working for some symbols, then all - a second indexing increases memory usage until it reaches around 1.8 gig. This is with only one core enabled. With all cores, it uses all available system memory and freezes the OS... typically when compiling.
