This is a problem with (at least some) Android versions. The setresgid and
setgid functions are in the C library, but actually calling it causes a
SIGSYS (Bad system call) signal to be sent.

This occasionally gets me too, attached is a patch that works around the
issue by not bothering to call the set*id functions when the effective IDs
already match real ones.
