Changes between Initial Version and Version 1 of Ticket #143, comment 12

initial	v1
5	5	Note that using fork means that we get rid of the exact sh specification in some places which in turn may require to either have EMXSHELL or SHELL set to sh or have /@unixroot/bin symlinked to /@unixroot/usr/bin (so that kLIBC finds sh even if EMXSHELL/SHELL isn't set). As this needs to be deployed on the user side as well, we will enhance the `os2-base` package to put these lines in CONFIG.SYS.

7		BTW, using the kLIBC path rewriter would be a better solution than EMXSHELL/SHELL because it would speed up exec/popen/system calls in kLIBC by reducing stat calls and variable checks a lot (the first hit of /@unixroot/bin/sh.exe hard-coded in kLIBC would immediately match). But that's a different topic I suppose.
