Comment(by nomeata):
I have applied all three patches to the GHC-7.4.1 package in Debian, but
from my testing it seems that the bug is really fixed, I still see much of
this when stracing xmonad:
{{{
--- SIGVTALRM (Virtual timer expired) @ 0 (0) ---
rt_sigreturn(0x1a) = -1 EINTR (Interrupted system
call)
poll([{fd=3, events=POLLIN}], 1, -1) = ? ERESTART_RESTARTBLOCK (To be
restarted)
--- SIGVTALRM (Virtual timer expired) @ 0 (0) ---
rt_sigreturn(0x1a) = -1 EINTR (Interrupted system
call)
poll([{fd=3, events=POLLIN}], 1, -1) = ? ERESTART_RESTARTBLOCK (To be
restarted)
}}}
Did I miss something? Did someone confirm with GHC-7.4.2 that this bug is
really fixed?
