Comparison of the posted system() & windll-based methods

tying to add a small quantitative comparison of latency overheads associated with two of the posted methods:

|>>> from zmq import Stopwatch
|>>> aSWX = Stopwatch()

|>>> from os import system
|>>> aSWX.start();system( 'TITLE os_SHELL_CMD_TITLE_TXT');aSWX.stop()  15149L [us]
|>>> aSWX.start();system( 'TITLE os_SHELL_CMD_TITLE_TXT');aSWX.stop()  15347L [us]
|>>> aSWX.start();system( 'TITLE os_SHELL_CMD_TITLE_TXT');aSWX.stop()  15000L [us]
|>>> aSWX.start();system( 'TITLE os_SHELL_CMD_TITLE_TXT');aSWX.stop()  14674L [us]
|>>> aSWX.start();system( 'TITLE os_SHELL_CMD_TITLE_TXT');aSWX.stop()  14774L [us]
|>>> aSWX.start();system( 'TITLE os_SHELL_CMD_TITLE_TXT');aSWX.stop()  14551L [us]
|>>> aSWX.start();system( 'TITLE os_SHELL_CMD_TITLE_TXT');aSWX.stop()  14633L [us]
|>>> aSWX.start();system( 'TITLE os_SHELL_CMD_TITLE_TXT');aSWX.stop()  15202L [us]
|>>> aSWX.start();system( 'TITLE os_SHELL_CMD_TITLE_TXT');aSWX.stop()  14889L [us]

|>>> from ctypes import windll
|>>> aSWX.start();windll.kernel32.SetConsoleTitleA('DLL');aSWX.stop()   5767L [us]
|>>> aSWX.start();windll.kernel32.SetConsoleTitleA('DLL');aSWX.stop()    643L [us]
|>>> aSWX.start();windll.kernel32.SetConsoleTitleA('DLL');aSWX.stop()    573L [us]
|>>> aSWX.start();windll.kernel32.SetConsoleTitleA('DLL');aSWX.stop()    749L [us]
|>>> aSWX.start();windll.kernel32.SetConsoleTitleA('DLL');aSWX.stop()    689L [us]
|>>> aSWX.start();windll.kernel32.SetConsoleTitleA('DLL');aSWX.stop()    651L [us]

In cases, where one might spend about a half of millisecond ( but not some tens of that ) the windll.kernel32 method seems promising and may serve better for an alternative display of a WatchDOG / StateVARs / ProgressLOG / auto-self-diagnostic messages, being efficiently displayed in a soft real-time need, during long running processes.
