update_meta_cache fails; query too large?

Description (last modified by nacin)
In the file meta.php, around line 183 in the 'update_meta_cache()' function, it tries to do a query but I noticed this can fail (ie. crash wordpress) if there are too many post id's in the query.
The function is being called from query_posts(), with 'posts_per_page' set to -1.
An example query that crashed it:
SELECT post_id, meta_key, meta_value FROM wp_postmeta WHERE post_id IN (1009,1006,989,933,902,860,859,858,857,793,838,837,836,827,825,310,780,777,776,775,774,773,770,763,760,759,758,757,728,756,755,754,753,752,751,750,748,746, 732,736,729,726,725,724,723,722,720,719,717,716,715,710,709,503,692,289,625,268,593,583,582,332,32,30,28,26,24,22)
Maybe there is some limit associated with queries of this type internal to wordpress, as this query works fine in phpMySql.
Apologies if this is already reported or irrelevant in 3.0!
