bump MAX_EFRAGS to 4096 (from 2048) and MAX_CHANNELS to 1024 (from 512). For ijed's map - has over 500 ambient sounds, causing it to hit the channel limit, and a lot of static entities, which I guess cause it to exceed the old efrags limit.   For future reference, according to mh, the efrags array can be removed entirely in glquake (http://forums.inside3d.com/viewtopic.php?t=1930) and each efrag allocated in the hunk memory.
