OS/2 uses the Posix codepath in subprocess.Popen that results in fork+exec to be used to start a new child. This is very inefficient on OS/2 given that parent data pages are deeply copied (Linux uses copy-on-write which is not available on OS/2 on the kernel level). Given that the subprocess interface clearly defines a child as having no any relation with the parent (other than regular file i/o inheritance and termination notification) this is a big overkill.

The WIndows code uses the StartProcess? WINAPI (which is exposed to Python). We may simply use the spawn C api (which is internally DosExecPgm?) and this looks like the right thing to do because fork on Posix there is a clear misuse (I guess there was no portable spawn implementation in Posix when this code was written).

Currently, errors output by warpin-conflicts.cmd, wps-object.cmd, etc. are not very useful to tools such as ANPM because we can't catch such output and present it to the user. Thus, the error is never displayed, and processing simply stops.

Suggestions for improving such output are in the related ticket in the Arca Noae Mantis:

There are a couple of use cases described there, as well.

arcanoae-exp is now a secure repo, so unauthenticated access is no longer allowed. If the package is maintained (for those who do not use ANPM's secure repo feature), I suggest it be installed disabled.

Preferably, however, the package should be removed from the repo entirely. Those who know how to deal with packages from arcanoae-exp should be able to figure out how to add it manually.
