Subject Re: [drlvm][threading] Some smoke tests started to hang this week on linux x86
Date Fri, 30 Mar 2007 02:53:49 GMT
The test gc.SynchronizedFinilazersTest hang up for me 3 times for 3
runs on SUSE 9 Linux x86_64 (jet mode). May be we exclude all these
tests up to end of investigation?

 thanks, Vladimir
