[Bluez-users] multithread / multi process use

Hello I'm new here, I searched for this issue but found nothing.

Using 2 threads or 2 process for reading a name of a 2 remote devices at
same time reports always the same name.
Is this a bug or the hci functions in library do not support concurrent use
?
(using 2.6.19 kernel on FC6 and bluez libs 3.7.1)

This is a simply way to reproduce this:

open a 2 shells and issue 2 commands at same time

hcitool name <bdaddress of a device close to you>

they both report the same name

here an HCI dump of what's happening

    status 0x00 bdaddr 00:17:4B:D3:9F:5B name 'Wince'

the second event with the second name is tracked but never reported back to
the caller cause the unknown event received.
so i see the name 'Seleso' as result on both the shells

this is the behaviour if I use the 2 command sequentially they works fine.

hcitool name 00:0A:28:DF:2B:D8

Since I need to use search names and search services (FAX especially) on a
multi-threaded application i'd like to know if is this possible or somewhere
there is a issue that prevent this.
