gc logging basic question

[Yu Zhang]

Tao,

GC logging is not part of GC STW pause. Though we may see application 
being stopped due to gc logging, if there are a lot of I/O activities on 
the system.
The gc log file is opened by the following
_fd = open(file_name, O_WRONLY | O_CREAT | O_TRUNC, 0666);

Thanks,
Jenny
