I started having strange hangs in various applications from yesterday,
e.g., Xorg, Thunderbird, etc.  Today, I updated ports tree from Git for
the first time and started updating packages.  Then, I experienced
similar problems, e.g., building editors/kate, multimedia/vlc, etc.,
were hanging.  I noticed some tools were stuck in urwlck state and I
found reverting this commit fixed the problem for me.

Please take a look.
