This has happened on 5.x for ages.  The quick fix is to ^Z, then fg, or
kill -CONT the hung strace process from another vty.  I don't know what
strace does different from truss that makes it hang.  Nowadays, truss
does almost as good a job as strace, so I don't use it as often as I
used to.  The only thing I miss is strace's ability to print the name
of blocking syscalls (read or sleep for example) as it waits.
