#11 Fix for a SIGTRAP signal handling

[Maxim Shchetynin]

When a simple program as following runs over strace and
receives a SIGTRAP signal then strace gets confused.

void main()
{
while(1) sleep(2);
}

The following patch is recommended to fix handling of a
SIGTRAP signal in strace.

Nice, but your fix breaks strace on 2.4 kernels.
Could you submit corrected fix, please?

Please add this. The 2.4.xx kernels are dead and buried.

Currently strace kills a process which takes a SIGSEGV
or similar, even if the signal handler would fix the
problem. (by updating EIP in the signal context, changing
permissions on a page, self-modifying the code, or just
never returning from the signal handler)
