Fails silently and hangs when cache directory is missing

[tdhooper]

Would be nice if it rendered the CSS, and reported the missing cache directory

yea, thats problably the cache-file-locking mechanism that gets stuck in a loop if the locking fails (could happen easily ob busy dev-servers). i removed all that on my branch, but thats crappy and therefore not yet public:)

i my opinion cache-thrashing would is less bad than deadlocks, but i'm not that dep in the guts of turbine yet to remove that safely:)
