svn commit: r234496 - stable/8/cddl/contrib/opensolaris/lib/libdtrace/common

[George V. Neville-Neil]

New Revision: 234496
URL: http://svn.freebsd.org/changeset/base/234496

Log:
  MFC: 234234
  
  Change SIGUSR1 to SIGTHR to properly wake up a process that is being
  traced.  The use of SIGUSR1 caused traced processes (those attached to
  with dtrace -p) to exit when dtrace exited.
