Theoretically that should not be possible as the XQuery whislt it is
executing will hold a READ lock. Whilst the READ lock is held, any requests
to update the XQuery will wait until the READ lock is released, each
pending update operation will then be executed one after another, with each
one taking the WRITE lock.

If there is a deadlock, there must be more resources involved than just the
XQuery.

Would it be possible to see a dump of the lock table when that happens
