[kaffe] solaris + pthreads hangs

[Riccardo]

Hello,

unfortunately at a clean build using KJC and pthreads on solaris, kaffe-
bin hangs:

[ parsed java/lang/ArithmeticException.java in 6,973 ms ]
<GC: heap 5124K, total before 4750K, after 3725K (49407/39486 objs)
 27.3% free, allocated 33752K (#82355), marked 518K, swept 1025K (#9921)
 9 objs (0K) awaiting finalization>
<hangs>

a gdb reveals

(gdb) bt
#0  0xef3b76e4 in door_restart ()
(gdb)

which is again that stupid place where it stopped some time ago. I don't 
remember how guilhem got past debugging this.
