PPSSPP is greedy for ram usage

[JumperTwo]

tested a few games now on both Windows and Android:

1) Ridge Racer 2 and The Third Birthday results are very good (30/35 mb after 20 minutes of gameplay)

2) Bleach Heat The Soul 7 runs ok (30/40 mb)

3) Mortal Kombat Unchained seems to indefinitely reserve memory and also very quickly (160/200 mb after less than 10 minutes)

sorry for making this sounds like a general issue, appears to be just MK
