        wip/paexec: Makefile distinfo

Log Message:

update to version 0.13.0

  FIXED: When 'paexec -s' retreives 10000 tasks, it allocates
  10000*10000*sizeof(int) bytes for detecting cycles, i.e. ~400Mb on
  32-bit system or 800Mb on 64-bit system. This is absolutely
  inacceptable. This bad algorithm is replaced with new one which
  doesn't need quadratic matrix and works much faster.

  ADDED: -Z<timeout> option
     When I<-z> applied, if a I<command> fails, appropriate node is
     marked as broken and is excluded from the following task
     distribution. But if B<-Z> applied, every I<timeout> seconds an
     attempt to rerun a comand on a failed node is made. I<-Z> implies
     I<-z>. This option makes possible to organize clusters over
     unreliable networks/hardware.

  No EINTR wrappers anymore (iread, xread etc.). SIGCHLD and SIGALRM
  are blocked most of the time. They are unblocked before select(2)
  and blocked just after it. SA_RESTART is not used anymore.

  Minor clean-ups in Makefile.
