? Interrupts the pyton?
What command are you using to send the signal to the process? That it should kill the wrong one is quite bizzare.

pthread_kill
PTHREAD_KILL(3) Linux Programmer's Manual PTHREAD_KILL(3)
NAME
pthread_kill - send a signal to a thread
SYNOPSIS
#include <signal.h>
int pthread_kill(pthread_t thread, int sig);
Compile and link with -pthread.
DESCRIPTION
The pthread_kill() function sends the signal sig to thread, a thread in the same process as the caller. The signal is asynchronously
directed to thread.
If sig is 0, then no signal is sent, but error checking is still performed; this can be used to check for the existence of a thread ID.
RETURN VALUE
On success, pthread_kill() returns 0; on error, it returns an error number, and no signal is sent.
ERRORS
EINVAL An invalid signal was specified.
ESRCH No thread with the ID thread could be found.
CONFORMING TO
POSIX.1-2001.
NOTES
Signal dispositions are process-wide: if a signal handler is installed, the handler will be invoked in the thread thread, but if the dispo-
sition of the signal is "stop", "continue", or "terminate", this action will affect the whole process.
