Subject: Re: Change signal mask after vfork/clone system call

> Now, I could unmask signals for the thread calling vfork, but it seems not a signal-safe solution to me because signals may arrive to this thread until I reestablish the mask. pthread_atfork call comes to rescue to address such issues for fork, but there seems to be nothing for vfork call.

Oh you are wrapping buggy apps ?

vfork
exec a tiny app which fixes the signals and execs the proper app

or fix the apps being run...
