Interesting!
Can I see the output of your SHOW FULL PROCESSLIST\G command please? Obviously, at the time when you see the locks.
it'd be nice if you also paste the output of SHOW CREATE TABLE <table name>; for tables involved.
Correction: A write will always get blocked by a running SELECT (unless you have concurrent_inserts=1/2 and there are no holes in your MyISAM table if concurrent_inserts=1)
