bracket not running the final action on termination through SIGTERM

If a program compiled with GHC receives a SIGTERM signal, while in a bracket, the final action of the bracket isn't executed. This can be tested with this program:

import Control.Exception
import Control.Concurrent

main = bracket (return "ending")
       (\x -> putStrLn x)
       (\_ -> threadDelay 10000000000)

When running this and interrupting with ctrl-c (thus SIGINT) it prints "ending", like expected. When interrupting it with killall -TERM test (assuming the program was named test) "ending" isn't printed and the program terminates immediately. It prints a system specific message though.
