[issue3551] multiprocessing.Pipe terminates with ERROR_NO_SYSTEM_RESOURCES if large data is sent (win2000)

[Hirokazu Yamamoto]

Hirokazu Yamamoto <ocean-city at m2.ccsnet.ne.jp> added the comment:

After googling, ERROR_NO_SYSTEM_RESOURCES seems to happen
when one I/O size is too large.

And in Modules/_multiprocessing/pipe_connection.c, conn_send_string is
implemented with one call WriteFile(). Maybe this should be devided into
some reasonable sized chunks for several WriteFile() calls?
