All rc scripts (except those ending in .sh) are sourced in a
subshell. Subshells' $$ is the same as their parents'.

It's a bit ugly and requires /proc being mounted, but this should work:

cd /proc/curproc && { thispid=${PWD##*/}; cd $OLDPWD; }

Or, ugly in another way:

thispid=$(ksh -c 'echo $PPID')
