* fhandler.h (fhandler_pty_master::~fhandler_pty_master): Delete.
* fhandler_tty.cc (fhandler_pty_master::~fhandler_pty_master): Ditto.
* sigproc.cc (sig_send): Set PIPE_NOWAIT for pipes which are not us.
* external.cc (fillout_pinfo): Remove nonsensical loop.
* fork.cc (frok::parent): When initializing pinfo for child new PID_NEW flag +
actual defined constant rather than raw number.  Don't set start_time here.
* pinfo.cc (pinfo::thisproc): Use PID_NEW when initializing pinfo.  Avoid
checking h for NULL multiple times.  Don't set start_time here.
(pinfo_init): Aways set ppid last.  Tweak strace output.
(pinfo::init): Handle new PID_NEW flag.  Wait for shared memory to contain
useful information.  Set start_time if PID_NEW.
(_onreturn:h): Define as HANDLE rather than HANDLE *.
(_onreturn::~onreturn): Accommodate h definition change.
(_onreturn::no_close_handle): Rename from no_close_p_handle.  Take a pinfo arg
and set hProcess to h before zeroing.
(winpids::add): Don't open a handle to our own process.  Change logic
associated with when a handle gets closed.  Accommodate no_close_handle
changes.
(winpids::enum_processes): Simplify process enumeration loop.
(winpids::set): Eliminate ill-considered malloc locking.
* sigproc.cc (proc_subproc): Always set ppid last.
* autoload.cc (timeBeginPeriod): Autoload.
* dcrt0.cc (dll_crt0_1): Use timeBeginPeriod to set default resolution to 1 ms.
* pinfo.cc (pinfo::thisproc): Set ppid for redirected _pinfo blocks too.
(pinfo::init): Avoid using VirtualQuery.  Just rely on the assumption that
procinfo will be populated.
* pinfo.h (_pinfo::ppid): Move into redirected block.
* autoload.cc (timeBeginPeriod): Delete.
* dcrt0.cc (dll_crt0_1): Use NtSetTimerResolution rather than timeBeginPeriod.
