conditional form is not consumed when :read-allow is falsey

Question

`
user=> (def a (java.io.PushbackReader. (java.io.StringReader. "#?(:clj [1 2])")))

'user/a

user=> (read a)
RuntimeException Conditional read not allowed clojure.lang.Util.runtimeException (Util.java:221)
user=> (read a)
(:clj [1 2])
`

the expected result would be an EOF exception on the second read.
