We intermittently observe copying artifacts to .m2 directory hungs.
Interestingly, it seems to happen at the specific artifact.

(*.nar is the artifact created by FreeHEP NAR plugin, which supports native code
(C++, fortrun, etc.) with maven. It's a just another type of zip file).

I could take the thread dump so attache them to this ticket. The problem happens
on build 1.210, and master, slave, and maven JDK are all jdk1.6.0_05.
