==Proposed patches==PR_CreateProcess in NSPR needs unicode support<br />[httphttps://jamesboston.ca/patches/patch092408bugzilla.txt <del>patch092408mozilla.txt<org/del>]: This patch fixes the kill() method by putting an attribute into the class that is a Win32 defined struct for holding a reference to a process, and then using that reference to terminate the process. This approach is not considered optimal because it adds more code complexityshow_bug.cgi?id=459572
[http://jamesboston.ca/==Submitted patches/patch092508.txt <del>patch092508.txt</del>]: This patch removes Window's specific code from the implementation. Instead, Windows and all other platforms use the Netscape Portable Runtime (NSPR) to create processes. Additionally, the logic for blocking is modified. For non-blocking processes, the code previously invoked logic in the NSPR that detached a process and deleted the reference to it, rendering the kill() function useless. This has been changed so that the kill() function works unmodified. However, it looks as the the NSPR does not support OS X process creation/termination. (In fact, the remaining Mac specific code in nsProcessCommon.cpp may not actually do anything.) Additional implementation may be necessary in the NSPR.==
[httphttps://jamesbostonbugzilla.camozilla.org/attachment.cgi?bugid=442393&action=viewall Bug 442393 patches/patch100308.txt patch100308.txt]: Removed the Mac code. The NSPR seems to do everything necessary. The destructor has also been coded Patches submitted to detach a process if it hasn't been killed yetfix Bug 442393 - nsIProcess.kill() does not work on Win32

[http://jamesboston.ca/patches/patch100308.txt Oct 3, 2008]: A patch that clears out Mac code as well. All platforms should be good now. [http://jamesboston.ca/patches/patch092508.txt Sept 25, 2008]: Revised patch to clear out some unused code.
