  18 # For instance, on Linux we need PTRACE_O_TRACEFORK set before the program
  19 # reaches the fork.  GDBserver was only setting flags when it reached the first
  20 # stop *after* arch_setup.  In a dynamic executable there is often a swbreak in
  21 # ld.so probes before reaching main, and ptrace flags were set then.  But a
  22 # static executable would just keep running and never catch the fork.
  23
  24 # Until "catch fork" is implemented on other targets...
