6.0-BETA: locked in lockmgr for fsync

[Bjoern A. Zeeb]

Hi,

this was on a 6.0-BETA machine in case anyone is interested.
Quick grepping didn't show me the same trace though there
were similiar looking once.
The machine was hanging completly, breaking to kernel debugger
was the only thing I could do. No debugging of locks though
so no show alllocks.
