I was in a similar situation once, don't really remember what it was,
though. What I did in that moment was

gdb -p $(pidof dwm) <<< 'call setenv("HTTP_PROXY","proxyhost:8080")'

(it was urgent)

One might also make dwm read a file/fifo with serialised key/value
environment variable pairs. But, this works, why bother?
