I tried the patch of Alexey,

i get
java.net.BindException: Address already in use ,
and
java.net.SocketException: Interrupted system call

and jboss doesnt seem to come up in relatively reasonable
amount of time. (its been 3 minutes since i started it,
whereas under green-threads/OpenJIT works fine).

Also i must note that native-threads seem to not work too.
(i had to play with -X* options to get it going and the performance
was way too bad:
Startup time for
green-threads/OpenJIT 14 secs
Linux Hotspot (On RedHat 7.1*) 30 secs
Native-threads/OpenJIT 45 secs
Hotspot (native) >= 3 mins

* On a similar machine (with more memory)

I must say that apart from the bad scaling the the green-threads/OpenJIT
solution shows, it rocks on atomic operations over the rest of
cases.

Anyway, now i dont get the SIGBUS
Java_java_net_InetAddressImpl_getHostByAddr
error.

Achilleus.

P.S.
Note that in order to build Hotspot a patch from some nice
japanese guys was needed. (i dont recall the message-id
but it is easy to find).
