Should they be converted back? And thus psutils has to convert them back again to Posix style? What will happen if a Cygwin process stores a windows path in its environment? Maybe each such variable should have a second variable in the Windows environment block that contains the Posix version of the variable and psutils picks that, in order to avoid round trip conversion inaccura- cies. Yea it's me again advocating against round trip conversions. Or we simply copy the variables unconverted to the Windows environment block, as the Windows env block is not used for anything else - up to now it is not updated at all.
