Ok... what about the following change:
Signal bits 0-63 are used or reserved for "normal" signals and signals
from 64-95 are used by realtime signals. Anything signal numbers from
96-128 are reserved.
This would allow 32 realtime signals (like in Linux) and avoid that they
have to move each time a signal gets added...
... would that work ?
Bumping the number beyond 64 is more work than I'd like to do.. also, as
Casper noted, the realtime signals are the ones that are actually suited
for moving, since SIGRTMIN and SIGRTMAX are defined as sysconf(2) calls.
The real issue here will be the value of NSIG, the number of signals.
This value is not in any standard, and its use is discouraged. But, it
is being used anyway, so its value will be compiled in to applications
(though not many), and it will have to change.
