 |This construct does not do what you expect.

Ok, but i think it is still a problem that this loops with 100%
percent CPU usage, endlessly.

 |Everything after #! goes into argv[1]:
 |
 |argv[0]='/usr/bin/env'
 |argv[1]='ABRA=KADABRA sh'
 |argv[2]='./script'
 |
 |and argv[2] is script's name. Thus, it won't work with any implementaion of
 |"env".

Isn't that a pity, what a terrible restriction, it would be so
nice to use.  (At least perl has this -x ... "#!perl" mechanism so
that no wrapper is needed at least there.)

And, not all env(1):

  ?0[steffen at devon shared]$ ./t.sh 
  hoho KADABRA haha
  ?0[steffen at devon shared]$ cat t.sh
  #!/usr/bin/env ABRA=KADABRA sh
  echo hoho $ABRA haha
  ?0[steffen at devon shared]$ strings /usr/bin/env 
  usage: env [-i] [name=value ...] [utility [argument ...]]
  $FreeBSD: src/usr.bin/env/env.c,v 1.11 2002/09/04 23:28:59 dwmalone Exp $

Much better, but not standard, unfortunately.
