patch pumpkin
patch pumpkin: n. [Perl hackers] A notional token passed around
among the members of a project. Possession of the patch pumpkin
means one has the exclusive authority to make changes on the
project's master source tree. The implicit assumption is that
`pumpkin holder' status is temporary and rotates periodically among
senior project members.
This term comes from the Perl development community, but has been
sighted elsewhere. It derives from a stuffed-toy pumpkin that was
passed around at a development shop years ago as the access control
for a shared backup-tape drive.
