PAR_CLEAN in PAR POD should likely be PAR_GLOBAL_CLEAN

[LouisStrous]

The POD in PAR.pm mentions PAR_CLEAN but setting an environment variable with that name to 1 on Windows 7 did not appear to have any effect. Setting PAR_GLOBAL_CLEAN to 1 had mostly the desired effect of cleaning up the cache, so I suspect that where the POD mentions PAR_CLEAN it should mention PAR_GLOBAL_CLEAN instead.

Setting PAR_GLOBAL_CLEAN had mostly the desired effect because afterwards a file 6b952d69.xs.dll of 19 kB in size remained in the par-/temp- directory. After multiple runs that file had the same name (but in different temp- directories). The clean-up code is not entirely successful.

The POD describes the cache location (with cleaning) as TEMP/par-USER/temp-PID/ and describes USER as being "the user name", but in my experience it is some hash value -- perhaps a hash of my user name.
