我在GVFS手册页中发现了一些内容，指出它是用于浏览Windows文件共享的。
• gvfsd-smb-browse - browses Windows Shares Filesystem volumes
GVFS是gnome虚拟文件系统：
GIO provides a VFS API to GLib applications. It includes a 'local'
implementation using POSIX. gvfs provides implementations that go
beyond that and allow to access files and storage using many protocols,
such as ftp, http, sftp, dav, obexftp, etc. It also provides support
for trash folders, for cd burning and for monitoring interesting
devices and volumes on the computer.
有在GVFS错误造成100％的CPU使用率，包括一些报告这一项是当前打开的。
